Audio Guide 3 Texas Instruments 1Q 2012 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.

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 wires are less than 10 cm. • A ferrite bead filter can also reduce very high-frequency interference. • For very stringent EMC requirements, place a 2nd-order low-pass LC filter as close as possible to the amplifier’s output pins.

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. Product Highlights DRV8662 (Piezo haptic driver) 200 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 30 LM48580 (Piezo/ceramic driver) 19 TPA2100P1 (Mono Class-D driver) 17.5 LM48556 (Ceramic driver) •DRV8662 oo Integrated 105-V boost converter oo Fast start-up time: 1.5 ms oo 1.8-V compatible digital pins oo Thermal protection oo QFN package Legend With Boost Converter 2 16.4 LM48557 (Ceramic driver, I C volume control) With Charge Pump LM48555 (Ceramic driver) 15.7 1.7 2.5 2.7 3.0 4.5 5.0 5.5 6.5 •LM48580 oo Class-H driver oo Integrated boost converter oo 3 pin-programmable gains oo Micropower shutdown oo 12-bump microSMD package Supply Voltage (V) Audio Guide 6 Texas Instruments 1Q 2012 Audio Amplifiers (Class-D) ➔ Design Considerations for Digital-Input Class-D 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) and speaker impedance. • Efficiency of Class-D amplifiers is typically between 80% and 90%, which reduces demands on power-supply designs when compared to Class-AB amplifier requirements. • 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.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio Audio Guide 9 Texas Instruments 1Q 2012 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.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio Audio Guide 11 Texas Instruments 1Q 2012 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.

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.

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.

For the latest information on audio end-equipment system block diagrams, visit www.ti.com/audio Audio Guide 14 Texas Instruments 1Q 2012 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.

Instruction Counter Instruction Memory Instruction Decoder Coefficient Memory Data In Data Memory Multiply Data Out and Accumulate • Three generations of miniDSP devices vary in terms of process and memory capability, resulting in 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 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.

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.

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) S/PDIF Interface Products and Sample-Rate Converters SRC4192/3 • 24 bit, stereo, 212-kHz Fs • 144-dB dynamic range • –140-dB THD+N • 28-pin SSOP • 2-channel combo SRC and DIX • 144-dB dynamic range • –140-dB THD+N • 48-pin TQFP • 24 bit, 4 channel, 212-kHz Fs • 144-dB dynamic range • –140-dB THD+N • 64-pin TQFP SRC4190 Performance SRC4392 SRC4194 SRC4382 SRC4184 • 24 bit, stereo, 212-kHz Fs • 128-dB dynamic range • –125-dB THD+N • 28-pin SSOP • 24 bit, 4 channel, 212-kHz Fs • 128-dB dynamic range • –125-dB THD+N • 64-pin TQFP PCM9211 • 2-channel combo SRC and DIX • 128-dB dynamic range • –125-dB THD+N • 48-pin TQFP • 216-kHz S/PDIF transceiver • 12x S/PDIF inputs • 3 I2S inputs, 2 I2S outputs • 101-dB stereo ADC • 48-pin LQFP DIX4192 • Pro S/PDIF/AES3 transceiver • Up to 24 bit, stereo, 216 kHz • 48-pin TQFP DIT4192 DIT4096 • Pro S/PDIF/AES3 transmitter • Up to 24 bit, stereo, 96 kHz and 192 kHz • 28-pin TSSOP DIR9001 • S/PDIF/AES3 receiver • DIR1703 replacement • Up to 24 bit, stereo, 96 kHz • Low 50-pS jitter DIX9211 • 216-kHz S/PDIF transceiver • 12x S/PDIF inputs • 3 I2S inputs, 2 I2S outputs • 48-pin LQFP Legend SRC S/PDIF, AES/EBU DIT - S/PDIF and AES/EBU Transmitter DIR - S/PDIF and AES/EBU Receiver DIX - S/PDIF and AES/EBU Transceiver Combo SRC Integration For a complete list of S/PDIF Interface and Sample-Rate Converters, see page 43.

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 • Excellent link budget with program- mable output power of up to +4 dBm and sensitivity of –83 dBm • Seamless support for CC2590 range extender • Suited for systems targeting compliance with worldwide radiofrequency regulations: ETSI EN 300 328 and EN 300 440 class 2 (Europe), FCC CFR47 Part 15 (U.S.) and ARIB STD-T66 (Japan) • Digital Audio Support • CD-quality uncompressed audio (44.1 or 48 kHz and 16 bits) • Digital I2S audio interface supports one or two audio channels (CC852x) or three or four audio channels (CC853x) at sample rates of 32, 40.275, 44.1 or 48 kHz with 16-bit word widths • Audio latency less than 20 ms • Data-side channel allows data to be sent alongside the audio between external host controllers Key Specifications • The built-in wireless audio protocol provides excellent robustness and coexistence through multiple techniques: • Adaptive frequency hopping • Forward-error correction buffering and retransmission • Error concealment • Optional high-quality audio compression • Antenna diversity • External System • Seamless connection and control of select TI audio codecs, DACs/ADCs and digital audio amplifiers using I2S and I2C • HID functions like power control, binding, volume control and audio channel selection can be mapped to I/Os • USB audio support (CC8521, CC8531) • RoHS-compliant 6 x 6-mm QFN-40 package • RF Section • 5-Mbps over-the-air data rate 3.7-V Li-Ion Battery (465 mAh) 3.7 V Applications • Wireless headphones/headsets • Wireless speaker systems • Wireless signal replacing cable • Wireless home theater systems • Wireless USB audio applications • Wireless microphones BQ25015 Charger with Integrated Synchronous Buck Converter Charge Indicator LED 2.0 V Wireless Headphone or Headset Reference Design • Cost-optimized design for high-quality headphones/ headsets • 100% longer battery life compared to today’s standard head sets (22 h on 465-mAh battery) • Consists of all-TI components TLV320AIC3204 L 2 2 R IN2L/R (Differential) IN3L/R (Differential) HPLOUT RF_N RF_P DVDD SDOUT SDIN MCLK SCLK LRCLK HPROUT CC8520 (Headphone) or CC8530 (Headset) SCL SDA RESET CC2590 Range Extender RF_N RF_P GIO7_AD0 GIO8_AD1 GIO14_xPAEN GIO15_xLNAEN PAEN EN GIO4_MCLK GIO4_BCLK GIO4_WCLK GIO1 GIO3 GIO9/I2S_AD2 GIO10_SCL GIO11_SDA GIO2_RESET Status LED Control Buttons For a complete list of PurePath™ Wireless Audio SoC solutions, see page 43.

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.
