What is the difference between an inverting and non-inverting amplifier?
A non-inverting amplifier produces an output signal that is in phase with the input signal, whereas an inverting amplifier’s output is out of phase. Both the inverting and non-inverting op amps can be constructed from one op amp and two resistors, just in different configurations.
What is an Inverting Amplifier?
An operational amplifier (or Op-Amp) which is designed to produce an output signal that is 180° out of phase with the applied input signal is called an inverting amplifier.
Therefore, in case of an inverting amplifier, if the input signal has positive phase then the amplified output signal will have negative phase and vice-versa. The inverting operational amplifier is the simplest and most extensively used configuration of the operational amplifiers.
The typical circuit of an inverting amplifier. From this circuit, it is clear that a feedback signal is provided in the operational amplifier so that the circuit can perform the closed loop operation. It may also be noted that the feedback provided is the negative one, which increases the accuracy of operation of the circuit.
