DESCRIPTION
The TPA6130A2 is a stereo DirectPath™ headphone amplifier with I2C digital volume control. The TPA6130A2
has minimal quiescent current consumption, with a typical IDD of 4 mA, making it optimal for portable
applications. The I2C control allows maximum flexibility with a 64 step audio taper volume control, channel
independent enables and mutes, and the ability to configure the outputs into stereo, dual mono, or a single
receiver speaker BTL amplifier that drives 300 mW of power into 16 Ω loads.
The TPA6130A2 is a high fidelity amplifier with an SNR of 98 dB. A PSRR greater than 100 dB enables
direct-to-battery connections without compromising the listening experience. The output noise of 9 µVrms
(typical A-weighted) provides a minimal noise background during periods of silence. Configurable differential
inputs and high CMRR allow for maximum noise rejection in the noisy environment of a mobile device.
TPA6130A2 packaging includes a 2 by 2 mm chip-scale package, and a 4 by 4 mm QFN package.

Headphone channels are independently enabled and muted. The I2C interface controls channel gain, device
modes, and charge pump activation. The charge pump generates a negative supply voltage for the output
amplifiers. This allows a 0 V bias at the outputs, eliminating the need for bulky output capacitors. The thermal
block detects faults and shuts down the device before damage occurs. The I2C register records thermal fault
conditions. The current limit block prevents the output current from getting high enough to damage the device.
The De-Pop block eliminates audible pops during power-up, power-down, and amplifier enable and disable
events.

Headphone Amplifiers
Single-supply headphone amplifiers typically require dc-blocking capacitors. The capacitors are required
because most headphone amplifiers have a dc bias on the outputs pin. If the dc bias is not removed, the output
signal is severely clipped, and large amounts of dc current rush through the headphones, potentially damaging
them. The top drawing in Figure 36 illustrates the conventional headphone amplifier connection to the
headphone jack and output signal.
DC blocking capacitors are often large in value. The headphone speakers (typical resistive values of 16 Ω or 32
Ω) combine with the dc blocking capacitors to form a high-pass filter. Equation 1 shows the relationship between
the load impedance (RL), the capacitor (CO), and the cutoff frequency (fC).
1
fc +
2pRLC O
(1)
CO can be determined using Equation 2, where the load impedance and the cutoff frequency are known.
1
CO +
2pRLf c
(2)
If fc is low, the capacitor must then have a large value because the load resistance is small. Large capacitance
values require large package sizes. Large package sizes consume PCB area, stand high above the PCB,
increase cost of assembly, and can reduce the fidelity of the audio output signal.
Two different headphone amplifier applications are available that allow for the removal of the output dc blocking
capacitors. The Capless amplifier architecture is implemented in the same manner as the conventional amplifier
with the exception of the headphone jack shield pin. This amplifier provides a reference voltage, which is
12
TPA6130A2

SLOS488A – NOVEMBER 2006 – REVISED DECEMBER 2006
connected to the headphone jack shield pin. This is the voltage on which the audio output signals are centered.
This voltage reference is half of the amplifier power supply to allow symmetrical swing of the output voltages. Do
not connect the shield to any GND reference or large currents will result. The scenario can happen if, for
example, an accessory other than a floating GND headphone is plugged into the headphone connector. See the
second block diagram and waveform in Figure 36.

Figure 36. Amplifier Applications
The DirectPath™ amplifier architecture operates from a single supply but makes use of an internal charge pump
to provide a negative voltage rail. Combining the user provided positive rail and the negative rail generated by
the IC, the device operates in what is effectively a split supply mode. The output voltages are now centered at
zero volts with the capability to swing to the positive rail or negative rail. The DirectPath™ amplifier requires no
output dc blocking capacitors, and does not place any voltage on the sleeve. The bottom block diagram and
waveform of Figure 36 illustrate the ground-referenced headphone architecture. This is the architecture of the
TPA6130A2.
Input-Blocking Capacitors
DC input-blocking capacitors block the dc portion of the audio source, and allow the inputs to properly bias.
Maximum performance is achieved when the inputs of the TPA6130A2 are properly biased. Performance issues
such as pop are optimized with proper input capacitors.
The dc input-blocking capacitors may be removed provided the inputs are connected differentially and within the
input common mode range of the amplifier, the audio signal does not exceed ±3 V, and pop performance is
sufficient.

SLOS488A – NOVEMBER 2006 – REVISED DECEMBER 2006
CIN is a theoretical capacitor used for mathematical calculations only. Its value is the series combination of the
dc input-blocking capacitors, C(DCINPUT-BLOCKING). Use Equation 3 to determine the value of C(DCINPUT-BLOCKING).
For example, if CIN is equal to 0.22 µF, then C(DCINPUT-BLOCKING) is equal to about 0.47 µF.
1 C
CIN =
(DCINPUT-BLOCKING)
2
(3)
The two C(DCINPUT-BLOCKING) capacitors form a high-pass filter with the input impedance of the TPA6130A2. Use
Equation 3 to calculate CIN, then calculate the cutoff frequency using CIN and the differential input impedance of
the TPA6130A2, RIN, using Equation 4. Note that the differential input impedance changes with gain. See
Figure 33 for input impedance values. The frequency and/or capacitance can be determined when one of the
two values are given.
1
1
fc IN +
or C IN + 2p fc R
2p RIN C IN
IN IN
(4)
If a high pass filter with a -3 dB point of no more than 20 Hz is desired over all gain settings, the minimum
impedance would be used in the above equation. Figure 33 shows this to be 37 kΩ. The capacitor value by the
above equation would be 0.215 µF. However, this is CIN, and the desired value is for C(DCINPUT-BLOCKING).
Multiplying CIN by 2 yields 0.43 µF, which is close to the standard capacitor value of 0.47 µF. Place 0.47 µF
capacitors at each input terminal of the TPA6130A2 to complete the filter.
Charge Pump Flying Capacitor and CPVSS Capacitor
The charge pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.
The CPVSS capacitor must be at least equal to the flying capacitor in order to allow maximum charge transfer.
Low ESR capacitors are an ideal selection, and a value of 1 µF is typical.
Decoupling Capacitors
The TPA6130A2 is a DirectPath™ headphone amplifier that requires adequate power supply decoupling to
ensure that the noise and total harmonic distortion (THD) are low. Use good low equivalent-series-resistance
(ESR) ceramic capacitors, typically 1.0 µF. Find the smallest package possible, and place as close as possible
to the device VDD lead. Placing the decoupling capacitors close to the TPA6130A2 is important for the
performance of the amplifier. Use a 10 µF or greater capacitor near the TPA6130A2 to filter lower frequency
noise signals. The high PSRR of the TPA6130A2 will make the 10 µF capacitor unnecessary in most
applications.
Layout Recommendations
Exposed Pad On TPA6130A2RTJ Package Option
Solder the exposed metal pad on the TPA6130A2RTJ QFN package to the a pad on the PCB. The pad on the
PCB may be grounded or may be allowed to float (not be connected to ground or power). If the pad is grounded,
it must be connected to the same ground as the GND pins (3, 9, 10, 13, and 19). See the layout and mechanical
drawings at the end of the datasheet for proper sizing. Soldering the thermal pad improves mechanical reliability,
improves grounding of the device, and enhances thermal conductivity of the package.
GND Connections
The GND pin for charge pump should be decoupled to the charge pump VDD pin, and the GND pin adjacent to
the Analog VDD pin should be separately decoupled to each other.
I2C CONTROL INTERFACE DETAILS
Addressing the TPA6130A2

TPA6130A2

SLOS488A – NOVEMBER 2006 – REVISED DECEMBER 2006
GENERAL I2C OPERATION
The I2C bus employs two signals; SDA (data) and SCL (clock), to communicate between integrated circuits in a
system. Data is transferred on the bus serially, one bit at a time. The address and data are transferred in byte
(8-bit) format with the most-significant bit (MSB) transferred first. In addition, each byte transferred on the bus is
acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with the master
device driving a start condition on the bus and ends with the master device driving a stop condition on the bus.
The bus uses transitions on the data terminal (SDA) while the clock is high to indicate start and stop conditions.
A high-to-low transition on SDA indicates a start and a low-to-high transition indicates a stop. Normal data-bit
transitions must occur within the low time of the clock period. These conditions are shown in Figure 37. The
master generates the 7-bit slave address and the read/write (R/W) bit to open communication with another
device and then wait for an acknowledge condition. The TPA6130A2 holds SDA low during acknowledge clock
period to indicate an acknowledgment. When this occurs, the master transmits the next byte of the sequence.
Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte). All compatible devices share
the same signals via a bidirectional bus using a wired-AND connection.
An external pull-up resistor must be used for the SDA and SCL signals to set the HIGH level for the bus. When
the bus level is 5 V, pull-up resistors between 1 kΩ and 2 kΩ in value must be used.

Register (N)
8- Bit Data for
Register (N+1)
Figure 37. Typical I2C Sequence
There is no limit on the number of bytes that can be transmitted between start and stop conditions. When the
last word transfers, the master generates a stop condition to release the bus. A generic data transfer sequence
is shown in Figure 37.
SINGLE-AND MULTIPLE-BYTE TRANSFERS
The serial control interface supports both single-byte and multi-byte read/write operations for all registers.
During multiple-byte read operations, the TPA6130A2 responds with data, a byte at a time, starting at the
register assigned, as long as the master device continues to respond with acknowledges.
The TPA6130A2 supports sequential I2C addressing. For write transactions, if a register is issued followed by
data for that register and all the remaining registers that follow, a sequential I2C write transaction has taken
place. For I2C sequential write transactions, the register issued then serves as the starting point, and the amount
of data subsequently transmitted, before a stop or start is transmitted, determines to how many registers are
written.
SINGLE-BYTE WRITE
As shown in Figure 38, a single-byte data write transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction of
the data transfer. For a write data transfer, the read/write bit must be set to 0. After receiving the correct I2C
device address and the read/write bit, the TPA6130A2 responds with an acknowledge bit. Next, the master
transmits the register byte corresponding to the TPA6130A2 internal memory address being accessed. After
receiving the register byte, the TPA6130A2 again responds with an acknowledge bit. Next, the master device
transmits the data byte to be written to the memory address being accessed. After receiving the data byte, the
TPA6130A2 again responds with an acknowledge bit. Finally, the master device transmits a stop condition to
complete the single-byte data write transfer.

Figure 39. Multiple-Byte Write Transfer
SINGLE-BYTE READ
As shown in Figure 40, a single-byte data read transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. For the data read transfer, both a write
followed by a read are actually done. Initially, a write is done to transfer the address byte of the internal memory
address to be read. As a result, the read/write bit is set to a 0.
After receiving the TPA6130A2 address and the read/write bit, the TPA6130A2 responds with an acknowledge
bit. The master then sends the internal memory address byte, after which the TPA6130A2 issues an
acknowledge bit. The master device transmits another start condition followed by the TPA6130A2 address and
the read/write bit again. This time the read/write bit is set to 1, indicating a read transfer. Next, the TPA6130A2
transmits the data byte from the memory address being read. After receiving the data byte, the master device
transmits a not-acknowledge followed by a stop condition to complete the single-byte data read transfer.

SLOS488A – NOVEMBER 2006 – REVISED DECEMBER 2006
Modes of Operation
The TPA6130A2 supports numerous modes of operation.
Hardware Shutdown
Hardware shutdown occurs when the SD pin is set to logic 0. The device is completely shutdown in this mode,
drawing minimal current. This mode overrides all other modes. All information programmed into the registers is
lost. When the device starts up again, the registers go back to their default state.
Software Shutdown
Software shutdown is set by placing a logic 1 in register 1, bit 0. That is the SWS bit. The software shutdown
places the device in a low power state, although the current draw is higher than that of hardware shutdown (see
the Electrical Characteristics Table for values). Engaging software shutdown turns off the charge pump and
disables the outputs. The device is awakened by placing a logic 0 in the SWS bit.
Note that when the device is in SWS mode, register 1, bits 7 and 6 will be cleared to reflect the disabled state of
the amplifier. All other registers maintain their values. Re-enable the amplibifer by placing a logic 0 in the SWS
bit. It is necessary to reset the entire register because a full word must be used when writing just one bit.
Charge Pump Enabled, HP Amplifiers Disabled
The output amplifiers of the TPA6130A2 are enabled by placing a logic 1 in register 1, bits 6 and 7. Place a logic
0 in register 1, bits 6 and 7 to disable the output amplifiers. The left and right outputs can be enabled and
disabled individually. When the output amplifiers are disabled, the charge-pump remains on.
HiZ State
HiZ is enabled by placing a logic 1 in register 3, bits 0 and 1. Place a logic 0 in register 3, bits 0 and 1 to disable
the HiZ state of the outputs. The left and right outputs can be placed into a HiZ state individually.
The HiZ state puts the outputs into a state of high impedance. Use this configuration when the outputs of the
TPA6130A2 share traces with other devices whose outputs may be active.
Note that to use the HiZ mode, the TPA6130A2 MUST be active (not in SWS or hardware shutdown).
Furthermore, the output amplifiers must NOT be enabled.
Stereo Headphone Drive
The device is in this mode when the MODE bits in register 1 are 00 and both headphone enable bits are
enabled. The two amplifier channels operate independently. This mode is appropriate for stereo playback.
Dual Mono Headphone Drive
The device is in this mode when the MODE bits in register 1 are 01 and both headphone enable bits are
enabled. The left channel is the active input. It is amplified and distributed to both the left and right headphone
outputs.
Bridge-Tied Load Receiver Drive
The device is in this mode when the MODE bits in register 1 are 10 and both headphone enable bits are
enabled. In this mode, the device will take the left channel input and drive a single load connected between
HPLEFT and HPRIGHT in a bridge-tied fashion. The minimum load for bridge-tied mode is the same as for
stereo mode (see table entitled "Absolute Maximum Ratings").

SLOS488A – NOVEMBER 2006 – REVISED DECEMBER 2006
Default Mode
The TPA6130A2 starts up with the following conditions:
• SWS = Off, CHARGE PUMP = On
• HP ENABLES = Off
• HiZ = Off
• MODE = Stereo
• HP MUTES = On, VOLUME = -59.5 dB,
VOLUME CONTROL
The TPA6130A2 volume control is set through the I2C interface. The six volume control register bits are decoded
to 64 volume settings that employ an audio taper. See Table 2 for the gain table. The values listed in this table
are typical. Each gain step has a different input impedance. See Figure 33.
