V in input voltage. The close loop gain of an inverting amplifier is given by. The following terms are used in the formulas and equations for operational amplifies.
V out output voltage.
Another useful application of an inverting amplifier is that of a transresistance amplifier circuit. A v voltage gain. V out output voltage. V in input voltage.
