Shall we use differential TDA7575B input as single ended

hi form members,

I am using audio amp. (TDA7575B) which has differential input (IN1+,IN1-) but in our case I have single ended input only from my codec, so i planned to connect IN1- pin to ground with a series capacitor. Is that OK else you have any specific recommendation please answer at the earliest.

REGARDS,

BALA

hi Bala,

yes , you can ground IN- through a coupling capacitor. but the value should be same with coupling capacitor for IN+.

thanks .
