I would like to take differential output from two photo darlingtons. I am biasing the photo darlingtons with 5 volt using LM7805. I am taking the output between the 10 k resistor and giving to opamp mcp602 with differential amplifier configuration without any gain. Is there any loading effect in my circuit? If yes does it require any buffer/voltage follower circuit in non inverting terminal? or how to improve my circuit? any other alternatives?
