Differential Amplifier Rechner — Formel
## Differential Amplifier
Amplifies the difference between two inputs while rejecting common-mode signals.
### Formula (matched resistors)
**V_out = (Rf / R1) x (V1 - V2)**
Requires R1 = R2 and Rf = Rg for proper common-mode rejection.

Requires R1 = R2 and Rf = Rg for proper common-mode rejection.
Lösungsbeispiel
V1 = 3 V, V2 = 1 V, R1 = 10k, Rf = 50k.
- Gain = 50 / 10 = 5 V/V
- Differential input = 3 - 1 = 2 V
- V_out = 5 x 2 = 10 V
