Hi ADI Expert,


I'm using the MEMs Mic (as attachment) with ADAU1961. 


And if I'm using ADAU1961's ALC function, the input need to be differential or pseudo input as datasheet mention in p.32. So the connection should be as below ? 


Input signal go into the "N" terminal and cap couple the "P" terminal to ground for a pseudo differential signal.


And for CM pin, just connect it with filter Cap?



Thanks very much!
