I made a photodiode preamplifier circuit for ADC. The op-amp IC is very difficult to find.
I have checked one altar, and find some information on google. Then I found such as OPA129 LMP7721 this class may worked. There are so many kinds of amps. The circuit structure is simple, is a reverse trans-resistance I - V structure, practice is more troublesome than theory. Could you give me some hint or instructions?
Could you help me check this out ? I just know a little about electricity. Please give me some help.
All the best
