I am debugging a 5613-prototype card, not the TAS5613 evaluation card. When power is on and reset is off, the amplifier is in a state where the CLIP signal is always on – even when there is no signal applied.
I am using components that are the same value or similar to the evaluation card which works in our application. When applying a sine wave signal to the input, the output does not look clipped, but the sound heard from the speaker is very distorted.
Any ideas on what the problem could be? Or where to start looking for problems?
Thanks,
Bruce
