DirectPath™  
Head Phone driver designed to reduce component  
count, board space and cost. It is ideal for single  
supply electronics where size and cost are critical  
design parameters.  
Eliminates Pop/Clicks  
Eliminates Output DC-Blocking Capacitors  
3 V to 3.6 V Supply voltage  
Low Noise and THD  
The TPA6139A2 does not require a power supply  
greater than 3.3V to generate its 25mW, nor does it  
require a split rail power supply.  
SNR > 105 dB at –1x Gain  
Typical Vn < 15 μVms 20-20kHz at –1x Gain  
Designed using TI’s patented DIRECTPATH™  
technology which integrates a charge pump to  
generate a negative supply rail that provides a clean,  
pop-free ground biased output. The TPA6139A2 is  
capable of driving 25mW into 32Ω and 2Vms into a  
600Ω load. DIRECTPATH also allows the removal of  
the costly output DC-blocking capacitors.

APPLICATION INFORMATION  
LINE DRIVER AMPLIFIERS  
Single-supply line-driver amplifiers typically require dc-blocking capacitors. The top drawing in Figure 9 illustrates  
the conventional line-driver amplifier connection to the load and output signal.  
DC blocking capacitors are often large in value, and a mute circuit is needed during power up to minimize click  
and pop. The output capacitor and mute circuit consume PCB area and increase cost of assembly, and can  
reduce the fidelity of the audio output signal.

Figure 9. Conventional and DirectPath Line Driver  
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.  
Combining this with the built-in click and pop reduction circuit, the DirectPath™ amplifier requires no output dc  
blocking capacitors.  
The bottom block diagram and waveform of Figure 9 illustrate the ground-referenced line-driver architecture. This  
is the architecture of the TPA6139A2.

COMPONENT SELECTION  
Charge Pump  
The charge pump flying capacitor serves to transfer charge during the generation of the negative supply voltage.  
The VSS capacitor must be at least equal to the charge pump capacitor in order to allow maximum charge  
transfer. Low ESR capacitors are an ideal selection, and a value of 1μF is typical. Capacitor values that are  
smaller than 1μF cannot be recommended as it limits the negative voltage swing in low impedance loads.  
Decoupling Capacitors  
The TPA6139A2 is a DirectPath™ amplifier that requires adequate power supply decoupling to ensure that the  
noise and total harmonic distortion (THD) are low. A good low equivalent-series-resistance (ESR) ceramic  
capacitor, typically 1μF, placed as close as possible to the device VDD leads works best. Placing this decoupling  
capacitor close to the TPA6139A2 is important for the performance of the amplifier. For filtering lower frequency  
noise signals, a 10-μF or greater capacitor placed near the audio power amplifier also helps, but it is not required  
in most applications because of the high PSRR of this device.  
Gain-Setting  
The gain setting is programmed with the GAIN pin individually for line driver and headphone section. Gain setting  
is latched when the MUTE pin is set high. Table 1 lists the gain settings. The default gain with the gain-set pin  
left open is –2x.

Input-Blocking Capacitors  
DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the  
TPA6139A2. These capacitors block the dc portion of the audio source and allow the TPA6139A2 inputs to be  
properly biased to provide maximum performance. The input blocking capacitors also limit the DC gain to 1,  
limiting the DC-offset voltage at the output.  
These capacitors form a high-pass filter with the input resistor, RIN. The cutoff frequency is calculated using  
Equation 1. For this calculation, the capacitance used is the input-blocking capacitor and the resistance is the  
input resistor chosen from Table 1. Then the frequency and/or capacitance can be determined when one of the  
two values is given.

For a fixed cutoff frequency of 2Hz the size of the input capacitance is shown in the table below with the  
capacitors rounded up to nearest E6 values. For 20Hz cutoff simply divide the capacitor values with 10; e.g., for

Pop-Free Power Up  
Pop-free power up is ensured by keeping the MUTE low during power supply ramp up and down. The pin should  
be kept low until the input AC-coupling capacitors are fully charged before asserting the MUTE pin high to pre-  
charge the ac-coupling; and, pop-less power-up is achieved. Figure 10 illustrates the preferred sequence.

CAPACITIVE LOAD  
The TPA6139A2 has the ability to drive a high capacitive load up to 220 pF directly. Higher capacitive loads can  
be accepted by adding a series resistor of 47 or larger for the line driver output.  
LAYOUT RECOMMENDATIONS  
A proposed layout for the TPA6139A2 can be seen in the TPA6139A2EVM User's Guide (SLOU248), and the  
Gerber files can be downloaded from http://focus.ti.com/docs/toolsw/folders/print/TPA6139A2evm.html. To  
access this information, open the TPA6139A2 product folder and look in the Tools and Software folder.  
Ground traces are recommended to be routed as a star ground to minimize hum interference. VDD, VSS  
decoupling capacitors and the charge pump capacitors should be connected with short traces.  
PIN COMPATIBLE WITH THE DRV612  
The TPA6139A2 stereo Headphone amplifier is pin compatible with the DRV612 . A single PCB layout can  
therefore be used with stuffing options for different board configurations.
