Howdy, I'm using the opa2350 op amp to amplify a <1mV signal by 2000. The problem is I want to have a greater gain (either second stage or larger feedback resistor) however the DC level is reaching too high so that it reaches over 2 V, and I need it under 2 V in order for a digital read into an Arduino. Does anyone have suggestions on how I can reduce the DC level? I would DC couple with a capacitor, however that would cut off half of my signal, and I would rather not do that. Any help would be greatly appreciated.
