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

Hi,

Please don´t use the datasheets provided by a distributor. Use the original datasheets of the manufacturer.

Then we need the specifications fo the circuit..and best: the circuit itself.

Electronics is: voltage, current, frequency... all technical values with units. But you don´t give a single value.

***
An amplifier amplifies a signal.
We need to know what is this signal (what are you interested in?):
* Is it DC (range, precision...)
* is it AC, what frequency?
* how much noise can you tolerate?
* what´s your supply voltage. Is it clean?..

All that´s important for you..(we don´t know)
