A non-inverting amplifier, commonly implemented using an operational amplifier (op-amp), has high input impedance. This means it draws very little current from the signal source. Its high input impedance makes it useful when the amplifier needs to avoid significantly loading the preceding circuit. The output signal is in phase with the input signal, meaning there is no 180° phase reversal.
A non-inverting amplifier has ______.
