I am designing an IA, but I am facing a problem in specifying the the CMRR of the amplifier in the specs. could someone help me.
 

specifying the CMRR

You can specify the CMRR across the frequency range you are interested at inputs = VCM.
Say DC = ?? dB
10Hz-1kHz = ?? dB

If you are in audio app, then you need to specify 10Hz-20kHz CMRR
 

specifying the CMRR

cmrr is interenal noise or error
