I need only one stereo input (2/3) and output (0/1) for ADAu1772 application.

Should I remove or mount input coupling and decoupling capacitors on unused AIN 0/1 and MIC pins?

Hello Traxman,

AIN 0/1 you want to cap couple to ground.

I think you are referring to the MICBIAS pins when you ask about the MIC pins? In that case they can be left floating.
