I reverse engineered a VOLTCON board that converts current from photo diode to voltage and drew the following schematic:
As per the data sheet (https://www.farnell.com/datasheets/3797110.pdf), POT1 varies the gain of the opamp. How does this change the gain when it is placed in parallel with the output of the opamp?
