This form of gain is measured when no feedback is applied to the op amp circuit. A load of 25 kω is connected to the output terminal. We will calculate the inverting gain of the op amp.
In an inverting op amp configuration the negative or inverting input labeled with the sign receives both the input signal v in and the feedback loop.
The formula for inverting gain of the op amp circuit gain av vout vin rf rin in the above circuit rf r1 10k and rin r2 1k. The formula for inverting gain of the op amp circuit gain av vout vin rf rin in the above circuit rf r1 10k and rin r2 1k. Negative feedback is used to control the gain of the overall op amp circuit. In the circuit shown below r 1 10 kω r f 100 kω v in 1v.
