A differential amplifier has a bias current of 100 n A, a maximum offset current of 20 n A, a maximum offset voltage of 2 mV, an input resistance of 1 MΩ, and a differential gain of 1000. The input terminals are tied to ground through (exactly equal) 100-kΩ resistors. Find the extreme values of the output voltage if the common-mode gain is assumed to be zero.
