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

Hi,
The OPA3S328 is a good option for this:
https://www.ti.com/product/OPA3S328
It has two high-precision amplifiers with fast settling to drive SAR ADCs, along with integrated switches, to be able to switch to multiple gain configurations.
Let me know…

Hi Ben,
I contacted the PGA280's designer and we still do not have the data to answer your questions directly.
Per PGA280's Mux input block, ESD diodes are before the mux switches and there are always a few on/off switches connected to the input…

And along these same lines, I was looking at this relatively new switched gain device the OPA3s328, these equations are correct where that one for Cf has that 4 in the denominator instead of 2. The extra 2 in the square root is essentially setting the…
