My customer is having a couple of issues with a custom board using the TAS5717:
1. With any I2S traffic, even with a silent audio, the output will oscillate at 8Hz. Tones will play on top of this low frequency and sound okay.
2. Any capacitance on the output (LC circuit) will cause the device to draw too much current and get hot. The inductor is 10uH and we tried 0.1uF and 0.47uF. Without any capacitance the problem goes away.
I can only share schematics via email.
Thank you!
