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.
