I recently bought the TPA3100D2EVM to do some prototyping work and verification. The eval board worked perfectly so I decided to integrate the TPA3100D2 chip into my PCB design. I followed the schematic and PCB artwork from the eval board. When I power up my board, the audio amp fault pin is always set to '1' (~4V). According to datasheet, this means that one of the output pins is shorted to ground, VCC, or each other. The weird thing is, that when I check for shorts with my meter, sometimes it indicates a short and other times it doesn't. And it varies on the different output channels. I have thoroughly investigated my PCB and schematic and there are no flaws in that regard. Does anyone have any ideas as to what I am seeing with my fault pin and the occasional short to VCC?
If this helps, here is my schematic without all the jumpers and such from the EVM board.
