I am trying to Configure an ADA4857-2 as an Instrumentation amplifier and I have simulated the circuit in ADS using the model and it is working fine. Now that I am making the schematics,I have encountered two pins which I do not know how to use and they are FB and PD pins.
I was thinking I need to instead of connecting my feedback path to the Output pin, I have to connect it to FB pin and I can just connect PD to ground. Is that correct?
Lastly,I would also like to ask a question on how to connect the common mode voltage to ADA4857-2
