    2021-5-29 · Two other features of a typical op-amp are: (a) the input impedance is extremely high, and (b) the output impedance is extremely low. Because the op-amp's gain is so high, even small differences in the inputs will rapidly drive the output voltage to its maximum or minimum value. For this reason, op-amps are usually connected to a negative feedback.
