Other Parts Discussed in Thread: TAS5806M
With my design is possible to play audio, and everything works fine if PVCC is kept betwen 5-8V. Above that voltage the PCB gets warm even when no Speaker is conneted, so something within my circuit must draw too much current. At 7 Volts it is about 0.12 Amps when ideling. I suspect it is the IC but I am not sure. My speaker has a DC resistance of about 3,5Ohm. Accordung to the Datasheet it should be possible to apply about 16V without Problems. Where did I make a Mistake?
