Part Number:LMP91000
In the datasheet for the LMP91000, it states that the max value for the TIA resistor (RTIA) is 350 kOhm. I am trying to measure a dissolved oxygen polarographic (2 wire) probe. The output is going to be in the 40-80 nA range, so I'd like to use something closer to 3-5 MOhms. That should output a few hundred mV- will this work out on the LMP91000? I just want to keep things in the best range for my ADC.
Best-
