Hi, I have a strain gauge going to an OPAMP (INA125P) with a BIG gain, and I am thinking that I need to put a high pass filter on the line. My question is should I do this before it goes to the OPAMP or after? If i do it before will it not just cause more noise on the circuit. Also, I'm thinking …

filters with OPAMPs

Please see the attached photo for reference.

Do you have your 5V and GND lines shorted together at the GND pin of the ADS1115 module?
