I am seeing current flow from the inputs of my OPA4188 op amp. It usually happens if one op-amp output in the quad package is railed. I thought this was a limitation of this type of op-amp.
Now I'm seeing 200uA coming out of the non-inverting node (pin 3). No amps in the package have inputs near the rails. The only output that railed is op-amp A, the one with 200uA at pin 3. Supply is 5V and GND. Pin 2 is at 2.21V. Pin 3 is at 1.45V. So the output is rightly at 0. But what could be causing the input current?
