#71338 - RE: Input signals to A/D - CMRR
Responding to: ???'s previous message
I don't know if it matters, but with the two R-C filters on the input to the INA, the Common-mode rejection will roll off significantly with higher frequencies. You might want to consider putting a larger differential capacitor into the circuit. See the following:
