Audio Amplifiers (Class-D)
➔ Design Considerations for Medium- and High-Power, Analog-Input
Class-D Speaker Amplifiers
Output Power per Channel
• Maximum power is decided
primarily by power supply (output
voltage and current) and speaker
impedance.
• Efficiency of Class-D amplifiers is
typically between 80% and 90%,
which reduces demands on the power
supply design.
• The maximum input signal level
dictates the required power amplifier
gain to achieve the desired
output power.
• For best noise performance, the gain
should be as low as possible.
Output Filter Design
• Most of TI’s Class-D amplifiers
operate without a filter when speaker
wires are less than 10 cm.
• When speaker wires are long, place
a second-order low-pass (LC) filter
as close as possible to the amplifier’s
output pins.
• The filter must be designed
specifically for the speaker impedance
because the load resistance affects
the filter’s quality factor, or Q.
• A ferrite bead may also eliminate very
high-frequency interference.
PCB Layout
• Place decoupling capacitors and
output filters as close as possible to
the amplifier IC.
• When using a ferrite bead filter place
the LC filter closest to the IC.
• Always connect the PowerPAD™
connection to the power ground.
• When the PowerPAD package serves
as a central “star” ground for amplifier
systems, use only a single point of
connection for the analog ground to
the power ground.

• The maximum input signal level
dictates the required gain to achieve

• For best noise performance, the gain
should be as low as possible.
• For louder volume from the speakers,
use a TI Class-D amplifier with an
integrated boost converter or
SmartGain™ AGC/DRC function.
• An integrated boost converter
provides louder volume at low
battery levels.
• Dynamic Range Compression (DRC)
increases the average volume,
optimizes the audio to fit the dynamic
range of the speaker and protects the
speaker from high power damage.
PCB Layout
• Place decoupling capacitors and
output filters as close as possible to
the amplifier IC.
• When using a PowerPAD™, connect
to the appropriate signal as per
TI datasheet.
Output Filter Design
• Most of TI’s Class-D amplifiers
operate without a filter when speaker

• A ferrite bead filter can also reduce

• For very stringent EMC requirements,

Audio Amplifiers (Class-D)
➔ Design Considerations for Piezo and Ceramic Drivers
Ceramic-Speaker Considerations
• Model the ceramic speaker impedance
as an RLC circuit with a large capacitance as its main element.
• Across most audio frequencies, the
ceramic speaker looks predominantly
capacitive.
• The capacitive nature of the speaker
makes its impedance inversely proportional to frequency.
• Calculate the impedance resonance
point above which the speaker is
much more ideal at producing sound.
• Exceeding the speaker terminal voltage
(typically 15 VPP) does not produce
more sound pressure, but it increases
the amount of distortion in the output
signal.
high voltage can be maintained over
frequency.
Benefits of Ceramic Amplifiers
• Fast slew rate.
• Fast turn-on time.
• High-output-current capability.
• Wide output-voltage range.
Heat
• Since ceramic speakers are much more
efficient than conventional dynamic
speakers, they dissipate less heat.

Output Voltage (VPP)
Output-Voltage Requirements
• Typically, 14 to 15 VPP at the output of
the amplifier is needed in order to produce the best level of sound pressure.
• The amplifier needs to be able to
drive large capacitive loads, given
the capacitive nature of the speaker
across the audio frequencies. This will
force the amplifier to deliver high output currents.
• Increasing voltage across the speaker
without exceeding the terminal voltage
increases the piezoelectric element
defection, which creates more sound
pressure and thus higher volume.
• The capacitive nature of the speaker
requires the amplifier to deliver high
output voltages and currents so that

Audio Amplifiers (Class-AB)
➔ Design Considerations for Class-AB Speaker Amplifiers
Output Power per Channel
• After determining the number of
speakers in a system, specify the
output power for each channel.
• Maximum power is decided
primarily by:
• Power supply (output voltage and
current)
• The amplifier’s maximum output
voltage
• Speaker impedance
• Maximum efficiency is –40% with
Class-AB amplifiers.
• The power supply must provide continuous current to support the desired
maximum power.
• The maximum input signal level dictates the required power amplifier gain
to achieve the desired output power.
• For best noise performance, the gain
should be as low as possible.
Heat
• Class-AB amplifiers run hotter than
equivalent Class-D amplifiers.
• Driving 2 W per channel in stereo
systems generates 6 W of heat with
an efficiency of –40%.
• TI’s Class-AB speaker amplifiers feature the PowerPAD™ package, using
a PCB as a heatsink.
• See the application brief
“PowerPAD™ Layout Guidelines”
for package layout and other design
considerations at:
http://www.ti.com/lit/sloa120
Features
• Class-AB amplifiers offer several
­different ways to control the gain
or volume:
• External resistors (similar to traditional op-amp circuits)
• Integrated gain-setting resistors
• DC volume control
• I2C volume control
• Most of TI’s portfolio provides the
three latter control options.
• When a headphone drive is part of
the design, most Class-AB amplifiers
can change outputs from bridgetied load (BTL) to single-ended (SE)
configurations, eliminating the need
for an additional amplifier.

Audio Amplifiers (Class-AB and Class-G)
➔ Design Considerations for Headphone Amplifiers
Issues to Consider When Using
Single-Ended Power Supplies
• Most amplifiers work with single
+3.3-V or +5-V supplies.
• These power supplies require a
DC-biased amplifier output to
ensure undistorted output.
• Placing DC-blocking capacitors
between the speaker and the
amplifier causes a high-pass filter and
equates to poor bass response.
• TI counters this high-pass filter
issue with capless and DirectPath™
technologies.
• Capless creates a virtual ground
(VDD /2) for the headphone
connector. Both amplifier outputs
then have a VDD /2 bias,
ensuring that no DC passes through
a speaker.
• DirectPath-enabled devices include
an internal charge pump which
creates a negative power rail inside
the device. With this design, an
amplifier can be powered by a
bipolar supply and have an output
biased to ground.
Headphone Impedance and Power
• Headphone impedances can vary
greatly, from 16 W to 600 W.
• When choosing an amplifier, always
ensure that it can handle the power at
the specified voltage range and headphone impedance.

➔ Design Considerations for Low-Power Audio Amplifier Subsystems
Radio Emission Interference in
Notebook PCs
• RF emissions from mobile data
add-in cards, 802.11 and Bluetooth®
radios can create noise problems for
amplifiers.
• It can be particularly problematic
if the amplifiers, codecs or speakers
are separated from each other
by industrial or board design
requirements.
• For additional design flexibility, use
devices with differential inputs, which
provide significantly better noise
immunity.
• The size and expense of DC-blocking
capacitors has led to capless
methods to implement output.
• VBias on ground sleeve removes
the caps, but can inject a hum
or damage the amplifier if ground
loopback occurs with an external
device.
• DirectPath™ solutions eliminate
ground loopback and improve bass
response.

Audio Amplifiers
➔ Design Considerations for Microphone Preamplifiers
Control Methods: Analog vs. Digital
• Analog control microphone preamplifiers typically use a variable resistor
on a product’s front panel that can be
changed during performance.
• Digitally-controlled microphones are
remotely controllable and have easily
recallable settings, offering significant
advantages when compared to their
analog control counterparts.
• In the live sound and recording industry, digitally controlled microphones
allow signals to be preamplified and
converted closer to the source rather
than sending tiny µV signals across
meters of cable.
Equivalent Input Noise (EIN)
Considerations
• EIN is a key specification in defining
a microphone preamplifier.
• At a given gain, microphone
preamplifiers exhibit a certain amount
of input noise that is amplified
together with the audio source.
• Ideally, microphone preamplifiers will
have low EIN values to ensure that
only the audio source is amplified
instead of the noise.
Outputs: Differential vs.
Single-Ended
• Inside a product, a single-ended
output is sufficient to process signals
needing further processing.
• Many high-performance ADCs
require differential inputs. If the
amplified differential microphone
signal is taken directly to an ADC, a differential output will give an
additional 6 dB of dynamic range.
• Differential outputs from a microphone
preamplifier will help ensure that the
differential input on the receiver
will reject any common-mode
interference induced on the cable by
cancelling out the common noise on
both connections.

Audio Amplifiers
➔ Design Considerations for Line Drivers/Receivers and
Operational Amplifiers
Driving 2 VRMS for Audio/Visual
Applications
• Almost all audio coming into a
television has a ground-centered
2-VRMS output.
• Most audio DACs have a sub-4 VPP
with a DC bias –2.5 V.
• The traditional solution for generating
a ground-centered 2-VRMS output is
to run an output op amp stage from a
higher voltage bipolar power supply
(±12 V).
• This solution adds complexity,
especially if the rest of the devices
are using only 3.3 V or 5 V.
• TI’s DRV60x family integrates the
amplifier and charge pump to create
positive and negative rails for clean,
ground-centered 2-VRMS output.
Balanced-Line I/O for Professional
Audio Applications
• Balanced-line I/O is used in
professional audio environments—
live, recording and broadcast—to
keep signals clean and
interference free.
• By having equal impedance to ground
on both conductors, balanced-line I/O
offers two advantages:
• The noise induced is near equal and
should be cancelled by a
balanced-line receiver as
common-mode noise.
• Having inverted signals on both
conductors also adds another
6 dB to the dynamic range for the
same supply voltage.
Overall Op Amps
• When selecting an op amp,
investigate its input stage.
• FET-based op amps usually have a
very high input impedance.
• FET-input devices are ideal when the
output impedance of the source isn’t
easily known, such as with a
musical instrument.
• BJT (bipolar)-based op amps exhibit
lower input impedance and offer lower
input noise.
• Bipolar op amps are ideal input
devices for low-impedance
output sources requiring low noise
amplification.

➔ Design Considerations for Volume Controls
Supply Voltage: Signal Swing
• DAC outputs typically have a swing of
around 3 VPP .
• Broadcast signal swings can easily be
25 VPP or higher.
• Knowledge of the signal amplitude
that will be attenuated is critical when
choosing digitally controlled analog
volume controls.
• For controlling DAC output, ±5-V
devices are more than adequate to
provide 10-VPP headroom for a
signal that, at maximum, will be
below 5 VPP .
Maintenance of Dynamic Range
• Multiplying the DAC’s digital value by
< 1 is an acceptable way to control
volume for many applications, using
fewer bits to represent the signal while
the noise level remains the same.
• Combining fewer bits to represent
a signal with a fixed-noise level will
increasingly reduce the dynamic range
as the volume changes.
• By changing the volume in the analog
domain while under digital control,
the DAC’s inherent noise will be
attenuated along with the audio.

Audio Converters
➔ Design Considerations for Portable Audio Codecs
The portable audio market is confronted
with many challenges. Design com­
plexity is leading towards thinner form
factors and higher-performance devices,
with continued pressure to achieve lower
power, smaller footprints and reduced
costs. In addition to the added com­
plexity from design constraints, the
market is requesting differentiated
devices that have real end-user perceived value. With many devices having
a life cycle of only 9 to 12 months
between versions, meeting these
­challenges requires expert understanding of the system and hardware/
software partitioning.
Reducing Noise on Microphone Inputs
• Microphone signals are susceptible
to noise injection because of the low
peak-to-peak range of 10 mV.
• Placing the codec or ADC close to
the microphone often conflicts with
user preference, industrial design or
mechanical design requirements.
• Look for devices that can work with
digital microphones or have differential
inputs, both of which provide
significantly better noise immunity.
Processing Allocation and Software
Reusability
• Host processors in handheld consumer
electronics are being given more tasks,
pushing processor MIPS allocations
and design schedules.
• One solution is to offload a number
of audio functions to a converter or
codec.
• Audio functions include 3-D effects,
equalization, notch filters or noise
cancellation.
• Look for devices with broad, easy
software reusability and the ability
to allocate the processing to either
input or output functions.
Simultaneously Handling Multiple
Audio Sources
• Designers of handheld consumer
electronics don’t have the option of
focusing on a single sample rate or
audio signal source. With multiple
functions come different radios and
sampling rates. Look for codecs with:
• Multiple independent analog and
digital interfaces.
• The ability to independently sample
and process these two signals.
Embedded miniDSP
• The miniDSP allows customers to run
advanced audio algorithms on the
audio codec. Running algorithms on
the codec:
• Optimizes system partitioning.
• Offloads the host processor.
• Simplifies regression testing.

• Three generations of miniDSP
devices vary in terms of process and

advanced audio and voice
improvements.
• Controls communication via I2C or
SPI and sends digital audio over I2S.
Supported formats include PCM,
DSP, L&R and TDM. Some devices
support more than one audio digital
interface.
miniDSP Components
• MAC: Performs digital signal processing calculations.
• Coefficient memory: Contains parameters for DSP programs (e.g., filter
coefficients).
• Data memory: Stores intermediate
audio sample data.
• Instruction memory: Stores miniDSP
program.
• Control units: Instruction counter and
decoder.
There is also a boot ROM, which provides:
• Bi-quad FIR filters.
• Multiband EQ, bass, treble, notch
filtering.
• Dynamic range compression/expansion
on playback path.
• Digital volume control and mono mixing.
• Beep generator, etc.
The miniDSP for Sound Enhancement
Microspeakers used in compact and
portable devices require significant
design compromises, such as non-ideal
enclosures, poor ventilation and limited
range of diaphragm motion, leading to
suboptimal sound quality and loudness.
The miniDSP can provide big sound from
small speakers, including sound field
expansion and psychoacoustic bass
enhancement for powerful bass without
a big subwoofer. The miniDSP can
support:
• Branded third-party algorithms. SRS
WOW-HD is a standard feature for all
miniDSP devices with stereo DAC.

➔ Design Considerations for Portable Audio Converters with miniDSP (Cont.)
• Due to resource limitations, complex
compression algorithms such as
AAC and MP3 are not supported.
• Multiband DRC and speaker-protection
algorithms to boost loudness and
sound quality without damaging the
speaker.
The miniDSP for Voice Enhancement
The miniDSP can provide significant
voice improvements in various types of
end equipment requiring:
• Single/dual-microphone noisesuppression algorithms at sampling
rates of up to 16 kHz.
• Acoustic echo cancellation and twomicrophone noise cancellation with
higher sampling rates and/or tail
lengths.
• Ambient-noise cancellation for widebandwidth noise attenuation.
More algorithms are always being
developed.
How to Use the miniDSP
Each miniDSP device can be programmed
via a graphical-development-environment
software called PurePath™ Studio. The
software is loaded on a host PC and used
to configure the codec and miniDSP and
to create process flows. Predefined com­
ponents are provided with a simple “drag/
drop” implementation of advanced audioprocessing flows. The miniDSP instruction
memory is loaded with the customized
desired algorithms over an I2C or SPI
interface.
PurePath Studio provides:
• An environment where no DSP programming experience is required.
• Easy-to-use GUI-control software to
control analog features.
• Extensive library of audio-processing
components.
Why Use a TI Audio Device with
Embedded miniDSP?
• Cost/Size—Can replace a codec and
dedicated signal processor in some
applications with a single chip:
• Systems needing noise and/or echo
cancellation.
• Systems needing audio processing
(speaker docks, headsets, etc.).
• Systems with SRS WOW HD, 3-D
effects, Dolby mobile.
• Faster Time-to-Market:
• Multiple-bus architecture allows for
complex audio applications without
audio mixing or routing by applications processor.
• Hardware/audio engineers can tune
system without developing complex
code that may have to go through
extensive regression testing.
• Audio tuning does not affect central
system processor.
• Added MIPS, offload processing from
main CPU.
• Save power by allowing muxing/
mixing to be done outside of applications processor.
• Customers with little audio experience
can leverage TI’s audio expertise (software, hardware and acoustics) to
improve sound quality.

Audio Converters
➔ Design Considerations for Portable Audio Converters
Reducing Noise on Microphone Inputs
• Microphone signals are susceptible
to noise injection because of the low
peak-to-peak range of 10 mV.
• Placing the codec or ADC close to
the microphone often conflicts with
user preference, industrial design or
mechanical design requirements.
• Look for devices that can work with
digital microphones or have differential inputs, both of which provide
significantly better noise immunity.
Processing Allocation and Software
Reusability
• Host processors in handheld consumer
electronics are being given more tasks,
pushing processor MIPS allocations
and design schedules.
• One solution is to offload a number of
audio functions to a DAC or codec.
• Audio functions include 3-D effects,
equalization, notch filters or noise
cancellation.
• Look for devices with broad, easy
software reusability and the ability
to allocate the processing to either
input or output functions.
Simultaneously Handling Multiple
Audio Sources
• Designers of handheld consumer electronics don’t have the option of focusing on a single sample rate or audio
signal source. With multiple functions
come different radios and sampling
rates. Look for codecs with:
• Multiple independent analog and
digital interfaces.
• The ability to independently sample
and process these two signals.

Audio Converters
➔ Design Considerations for Portable Audio Converters with Integrated
Touch Screen Controller
Using Touch Screen Controllers
(TSCs) to Offload Host Processing
• TSCs detect contact and then
require the host to handle as many as
40 to 50 register read/write cycles.
• These requirements create additional
interrupts and processing cycles,
which reduces processing efficiency.
• To reduce this load on the host, look
for “smart” TSCs with the ability to
generate coordinates with minimal
interaction from the host.
Other Methods for Using TSCs to
Offload Host Processing
• Host processors in handheld
• consumer electronics are being given
more tasks, pushing processor MIPS
allocations and design schedules.
• One solution is to offload a number of
audio functions to the DAC or codec
functions of a TSC.
• Audio functions include 3-D effects,
equalization, notch filters or noise
cancellation
• Look for devices with integrated
audio, software reusability and the
ability to allocate the processing to
either input or output functions
Supporting Varying Mechanical
System Designs
• The preferred solution with a single
integrated TSC + audio device or a
discrete TSC and audio codec may
depend on whether a handheld device
is built on:
• A single-board platform, such as a
candy bar
• A PDA form factor
• An in-dual board platform like a
flip phone
• TI offers a wide selection of standalone TSCs and audio codecs as well
as integrated TSC + audio devices for
all types of system designs.

Performance Audio Converters
➔
Design Considerations for Performance Audio Converters
Dynamic Range
• Home and professional audio
converter performance is measured in
dynamic range, not bit depth.
• A 24-bit converter describes its output
format, not its quality.
• Therefore, many of the least
significant bits in a 24-bit audio word
may be noise.
• At its peak, a standard CD has
98.08-dB (16-bit) dynamic range.
• In professional environments, a
converter may have a dynamic range
of up to 132 dB.
Analog Integration and Multichannel
Support
• TI’s highly integrated range of
consumer converters support
complex signal-chain designs.
• Integrating functionality such as
multiplexers, programmable gain
and S/PDIF transmitters into a single
package reduces cost, design
complexity and time to market.
Control Methods
• Converters can be controlled in many
different ways; many simply by tying
pins high and low.
• A small micro, SPI shift register or I2C
expander can allow control from a
remote source.
• For products with increased
integration, control is typically through
either SPI or I2C.
• When choosing converters or codecs,
confirm both the control method and
the existence of additional I/O (GPIO,
SPI or I2C) for the main processor to
support the device.

Interface and Sample-Rate Converters
➔ Design Considerations for S/PDIF Interface and
Sample-Rate Converters
Sample Rate Converters (SRCs)
• SRCs create sample rate and phaseindependent interfaces between fixedrate digital processors and the outside
world.
• SRCs can serve as “jitter cleaners,”
lowering the amount of jitter
on incoming data streams.
• SRCs allow similar phaseindependent sample rates to be
brought into systems without the
need for time alignment/word clock
distribution.
Jitter Sensitivity
• Jitter can be a major problem in a
digital audio system.
• Jitter is introduced when digital audio
clocks are generated or regenerated
from a different clock source and by
using interconnects that have
significant parasitic impedance
(capacitance, inductance, etc.).
• Jitter in digital audio systems moves
the sampling instant back and forth in
time, adding noticeable distortion in
high frequencies.
• For the smallest adverse impact on
the audio content, choose S/PDIF
receivers with low jitter.
System Partitioning
• System partitioning options include
discrete transmitters, receivers and
stand-alone SRCs, as well as
combinations of transceivers
and SRCs.
• Flexible functionality allows end
­products to be either:
• A clock master (and SRC from the
outside to its internal process clock)
• A slave to an external clock
(and SRC the output to the new
clock rate)

2.4-GHz PurePath™ Wireless Audio SoCs
➔ Design Considerations for PurePath Wireless Audio SoCs
Overview
By employing proprietary technology
called PurePath™ Wireless, the CC85xx
RF IC device family provides high-quality,
short-range, 2.4-GHz wireless digital
audio streaming in cost-effective singlechip solutions. Two or more devices form
a PurePath Wireless audio network. Great
care has been taken to ensure that this
network provides gap-less and robust
audio streaming in varied environments
and that it can coexist amicably with
existing wireless technologies in the
crowded 2.4-GHz ISM band. Most applications can be implemented without any
software development and only require
the CC85xx to be connected to an
­external audio source or sink (such as an
audio codec, S/PDIF interface or Class-D
amplifier) and a few push buttons,
switches or LEDs for human interaction.
Advanced applications can interface a
host processor or DSP directly to the
CC85xx to stream audio and control
most aspects of device and audio-­
network operation.
The PurePath Wireless Configurator, a
PC-based configuration tool, is used to
set up the desired functionality and
parameters of the target system. It then
produces firmware images that subsequently must be programmed into the
embedded flash memory of each CC85xx.
All devices in the CC85xx family interface
seamlessly with the CC2590 RF rangeextender device to allow for even wider
RF coverage and improved robustness in
difficult environments.
• Bandwidth-efficient modulation format

➔ Design Considerations for Audio Controllers and Converters
with USB Interface
Programmable vs. USB Codecs
• For designers with little USB
experience, one of the biggest
challenges is deciding between a
plug-and-play device and one that
requires coding.
• TI codecs (PCM2xxx) deliver an
extremely simple plug-and-play experience by being completely USB-class
compliant.
• For the highest flexibility and
performance defined by an
external converter, the TAS1020B
and TUSB3200A offer completely
programmable solutions based on an
8052, 8-bit processor core.
I/O Considerations (S/PDIF, I2S, HID)
• Beyond analog audio in and out, many
USB audio products now offer:
• S/PDIF I/O
• Raw PCM data (in I2S form)
• Human interface device (HID)
functionality
• HID functionality allows control of
PC/Mac applications:
• Mute, volume up/down, play, stop,
rewind, fast-forward, etc.

Analog Switches
➔ Design Considerations for Analog Multiplexers and Switches
Audio Headset Type Detection and
Switching
• Audio headsets come with or without
a microphone pin, and the microphone
and ground pins can be in different
configurations.
• Circuitry is therefore required to detect
the presence of an analog microphone
and the configuration of the microphone
and ground pins and then switch the
system connections appropriately.
• Sometimes the detection circuitry is
integrated into the audio codec, and
the switch performs only the switching
function, as in the TS3A26746E.
• There are advanced switches, such as
the TS3A225E, that integrate both the
detection and switching functions in a
single IC.
On-State Resistance (ron) Tradeoffs
• ron contributes to signal loss and
degradation.
• Non-charge-pump switches achieve
low ron with large pass transistors.
• Leads to larger die sizes and
increased channel capacitance (CI/O)
• Limits the frequency response of the
switch
• Switches using charge-pump technology can achieve low ron and CI/O but
require significantly higher I+.
On-State Resistance Flatness [ron(flat)]
• On-state resistance flatness specifies
the minimum and maximum value of ron
over the specified range of conditions.
• Conditions may include changes in
temperature or supply voltage.
Negative Signal I/O Capability
• Switches that interface with
“cap-free” headphone amps such
as the TPA6130A2 from TI need to
be able to support audio signals that
swing below ground.
• When used with audio amps that use
a DC-blocking capacitor, switches that
are placed between the audio jack and
the blocking capacitor need to support
audio signals that swing below ground.
Specified Voltage Range (V+)
V+ and the Max Analog Signal
Amplitude
• V+ determines the analog signal amplitude that can be passed without clipping for noncharge-pump switches.
• The gate(s) of the pass transistors must
be biased relative to the minimum and
maximum values of the expected input
voltage range.
• Some switches feature negative signal
capability and allow signals below
ground to pass through the switch with­
out distortion, making it easy to pass
both positive and negative
signals.
Analog
• Switches with integrated
charge pumps can elevate the
5
gate voltage above V+ (at the
expense of larger I+) and thus
pass signals of a magnitude
4
greater than V+.
VIH/VIL Compatibility
• The signal switch is controlled
by the output of a digital
source in most applications.
• The control signal levels, VIH
and VIL, must be compatible with the digital source to
ensure proper operation of the
switch.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
