Part Number: OPA328 Other Parts Discussed in Thread: OPA3S328 , Tool/software: Hi Ti,
I'm having trouble identifying the issue with my model, which is set for a lower gain of 500 ohms using the OPA3S328 dual-channel op-amp in a transimpedance configuration…
Hello PG,
Please check out OPA328 vs. OPA340 . It is better op amp for TIA application. OPA3S328 is a dual channel version of the precision op amp + some additional features.

Hi Grady,
What input ranges do you need? Could we discuss it via email in detail?
For automatic gain control, we could use external programmable gain amplifiers or amplifiers with multiplexers, and comparators to automatically switch gains.
Some options…
HI Henry,
As alternate solutions, you could consider using a programmable gain transimpedance amplifier or a Logarithmic amplifier solution.
Since the application requires to measure a wide range of current, from 10nA to 1mA., and if the application requires…

Dear Katlynne,
for the PGA I found the PGA117AIPWR or the OPA3S328 in stock! I think to take the OPA3S328. Sorry for previous schematic, the voltage for PGA is 5V0 solution 2).
thanks for your return
