ONE FORMULA, ONE ANSWER
Noninverting Op Amp Gain Calculator
Calculate ideal noninverting negative-feedback voltage gain. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Noninverting voltage gain A_v
Enter values and select Calculate.
A_v = 1+R_f/R_g
Assumptions
Required: R_f≥0, R_g>0 and linear negative-feedback operation of an ideal op amp. Supply-rail saturation, bandwidth, offset and output loading are excluded.
Displayed values are floating-point approximations. Design safety factors and unprovided error contributions are not calculated.
