SLOS700C January 2011 – April 2016 TPA6139A2
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
A proposed layout for the TPA6139A2 can be seen in the TPA6139A2EVM User's Guide (SLOU308), 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.
TI recommends routing the ground traces as a star ground to minimize hum interference. VDD, VSS decoupling capacitors, and the charge pump capacitors should be connected with short traces.
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.
