Inverting Op-Amp Resistor Calculator 

See our other Engineering Calculators.

This calculator determines the bias and feedback resistors for an op-amp, given the gain and desired output bias point.  There are many free parameters to the design so enter the value of R1, which will scale the other resistors.  Use V1 as the input for the inverting Op-Amp, and V2 as a voltage offset if needed.  Set V2 to zero if no offset is required. 


Input Parameters (Inverting Op-amp)
Vout (V) 
R1 (KOhms)
V1 (Input lead) (V) 
V2 (non-zero only if offset is requred) (V)
Vp (V)
Vn (V)

R2 (KOhms)
R3 (KOhms)
R4 (KOhms)


Op-Amp Manufacturer Links

The best way to find op-amps is to use our free Electronics Component Directory, where a myriad of op-amp manufactures are listed.
