Non-Inverting Op-Amp Gain Rechner — Formel
## Non-Inverting Op-Amp Configuration
### Formula
**Gain = 1 + Rf / R1**
**V_out = (1 + Rf / R1) x V_in**
Output is in phase with input. Minimum gain is 1. Input impedance is very high, set by the op-amp input stage.
### Formula
**Gain = 1 + Rf / R1**
**V_out = (1 + Rf / R1) x V_in**
Output is in phase with input. Minimum gain is 1. Input impedance is very high, set by the op-amp input stage.
Lösungsbeispiel
R1 = 10k, Rf = 90k, input signal is 1 V.
- Gain = 1 + 90 / 10 = 10 V/V
- Gain in dB = 20 x log10(10) = 20 dB
- V_out = 10 x 1 = 10 V
