Just to get the ball re-rolling..... So I am playing with a simple op-amp circuit to test a new PCB. I just need a quick adjustable gain so I threw a pot in the feedback path in a non-inverting configuation... Normally in a op-amp gain circuit I would fix the gain and add an attenuator before or after the gain stage , depending on what I would was trying to do. I typically do this improve the stability of the gain stage. So my question is … Do you put your gain adjustment in the feedback path in any of your circuits? And what are reasons for doing so?
