The company where I am working have implemented a light detector circuit involving PIN photodiodes and Opamps. (as attached)
The problem I see is that the LMV321 opamp has a 3V3 rail and yet a 2V7 input, which is above the common mode input range of the LMV321 opamp.
Do you agree that this circuit is suboptimal?
