Common Photodiode Op-Amp Circuit Problems

Common Photodiode Op-Amp Circuit Problems and Solutions

Analog Devices Inc

This presentation will define the photodiode op-amp circuit and discuss the basic requirements for proper operation. The most common problems with photodiode op-amp circuits will be reviewed along with suggestions for possible causes and fixes for the problems. Finally, there will be a review of op-amp selection, and a listing of op-amps offered by ADI.
