Inverting op-amp

Inverting op-amp gain calculator calculates the gain of inverting op-amp according to the input resistor Rin and feedback resistor Rf. The gain indicates the factor by which the output voltage is amplified, i.e. it tells how many times the output voltage will be than the input voltage. The equation to calculate the gain is given below

Gain  = Rf/Rin

For example if the gain is 5, then the output voltage will be 5 times greater than the input voltage.

Non inverting op-amp

This non-inverting op-amp gain calculator calculates the gain for non-inverting op-amp according to the below equation, where Rin is the input resistor and Rf is the feedback resistor.

 Gain = 1 + Rf/Rin
