I'm trying to amplify a signal in the mV range. Say I have a base signal of 1.000v. And I want to amplify that 3000 times, so 1.001v signal will output as 3v from opamp output.
So I'll have a reference voltage of 1.000v fed into the opamp, and have it listen to the signal. Am I correct in that if I want to measure 1mv accurately, I need an opamp with an input offset voltage spec much lower than 1mv for it to work correctly?
