I am having two different electrochemical processes. Mathematically one is having a voltage which is of order 2uV, and another is having current from 100nA to 2uA that I need to measure. Both are DC. Can you please suggest ADI op-amps or instrumentation amplifier that I need to incorporate into my design so that I can move further to my product phase.
I had a lot to search at your website but doesn't get any good information.
