Hi everyone,
I have a 1mA DC current that I am going to run through a 100ohm resistor to convert to a voltage and send to input of an opamp. I need low noise so I can detect at least a 10uA change in the DC current. I searched digi-key and there are so many that seem to work for my application. Does anyone have any suggestions for specific surface mount parts to look into that are low noise with good dc characteristics? Also, I need it to run from a single voltage supply of 3V or less.
Thanks,
ed
