How To Calculate Op Amp Gain

Op-Amp Voltage and Gain Calculator - Engineering …

https://www.allaboutcircuits.com/tools/op-amp-voltage-and-gain-calculator/

Note that this calculator can be used for either an inverting or a non-inverting op-amp configuration. For a non-inverting op-amp, set V2 to 0V and use V1 as the input. If an inverting op-amp is desired, set V1 to 0V and use V2 as the input. Use a very large value for R3 (e.g., 9999999999) if the op-amp's positive input terminal s… See more
