Inverting Amplifier	Non - Inverting Amplifier
A type of amplifier whose amplified output is 180 degrees out of phase with the input signal.	A type of amplifier whose amplified output is in-phase with the input signal.
The input and output signal has 180 degrees of phase difference.	The input and output signals are in-phase or have a 0 degree phase difference.
The input signal is applied at the inverting terminal.	The input signal is applied at the non-inverting terminal.
The non-inverting terminal is grounded.	The inverting terminal is grounded through a resistor.
Its gain is given by Av = -(Rf / Ri).	Its gain is given by Av = 1 + (Rf / R).
It has a lower gain than a non-inverting amplifier.	It has a relatively higher gain.
It has a negative voltage gain.	It has a positive voltage gain.
