As shown below:
What is the function of capacitor C1 and capacitor C2 in the circuit?
What role does capacitor C1 have besides differential mode filtering?
Nico Publicado en December 9, 2020
Provide a loop for the input current because the input impedance of the op amp is very large.

The function of capacitor C1 is to provide a loop of input current? ? Is it an AC signal?

It should all be to filter out some noise or ripple.

They are all filtering effects. The value of C1 should be small. The circuit I have seen takes pF and is close to the pin. The value of C2 depends on the filtering effect!
