Consider an op-amp where the inverting input voltage =3.7mv, non-inverting input voltage=6.25mv and open loop voltage gain =142dB. Find the output voltage.

Consider an op-amp where the inverting input voltage =3.7mv, non-inverting input voltage=6.25mv and open loop voltage gain =142dB. Find the output voltage. Correct Answer 0.36v

Open loop voltage gain, AoL(f) = Vo/Vid VO = AOL(f) × (Vin1-Vin2) = 142 dB×(6.25-3.7) = 142×2.55 = 0.36v.
