Hi. I purchased an LMP91000SDEVAL board to be evaluated for 3 electrode sensor. Our plan is to put 0.5V between WE and RE. The current I am expecting to read is from 10nA to 200nA. Will LMP91000 works for this current range? I would like to know the suggested settings on Vref, Vdd, TIA. The Vout will be going to an ADC with Vref of 2.5V. Thanks.
below the setting of the LMP91000 and external supply/Reference.
Bias: 20% VREF
RTIA = 350Kom
Internal Zero = 67% VREF (I'm assuming the current is entering in to the WE pin of the LMP91000),
