Wideband Differential Amplifier Calculator
Calculate the differential gain of a wideband differential amplifier using:
\[
A_d = \frac{R_2}{R_1}
\]
Optionally, if the op-amp’s gain–bandwidth product (GBW) is known, estimate the -3 dB bandwidth:
\[
f_{3dB} = \frac{\text{GBW}}{A_d}
\]
* Enter resistor values in ohms and GBW in Hz (optional).
