using both outputs: this is called differential output; When using differential amplifiers, two different gains can be calculated: the differential gain, and the common-mode gain. The differential gain is determined with a differential input signal, while the common-mode gain is determined with the same signal applied at both inputs.Differential Amplifier Gain The gain of a difference amplifier is the ratio of the output signal and the difference of the input signals applied. From the previous calculations, we have the output voltage V OUT as. V OUT = R 2 / R 1 (V 1 V 2) So, Differential Amplifier Gain A D is given by. A D = V OUT / (V 1 V 2) = R 2 / R 1.Differential gain is the gain by which the amplifier boosts the difference of the input signals.
