If it is a scaled fraction then how does it get filtered from transient changes of the Vdc supply?If it is a fixed constant voltage then the outputs will be biased at that same voltage and peak output audio will be clipped non-symmetrical. For examp...

Thank you, Peter!I agree with your suggestion that it should be better to add an active high-pass filter instead of relying on the input coupling cap.

Thank you for the prompt answer, Peter!My plan was to use the TDA7376B to drive a stereo pair of smaller speakers in a bi-amped (2.1 channel) system, with a mono class D amp for the woofer. I was going to use the input coupling caps into the TDA7376B...

TDA7376B 2 channel power amplifier How is the internal Vref controlled? Is it a fixed, constant voltage? or is it a scaled fraction of the main power supply Vdc?
