In Electronics, an Operational Amplifier (Op-Amp) is a highly versatile integrated circuit used to boost weak electrical signals. Depending on how you connect the input signal, an Op-Amp can be configured as an Inverting or a Non-Inverting amplifier.
Component: Based on Operational Amplifiers (Op-Amps).
Inverting: Flips the signal upside down (180° shift).
Non-Inverting: Amplifies the signal while keeping it upright (0° shift).
| Feature | Inverting Amplifier | Non-Inverting Amplifier |
|---|---|---|
| Input Terminal | Negative (-) | Positive (+) |
| Phase Shift | 180 Degrees | 0 Degrees (In phase) |
| Gain Formula | -Rf/Rin | 1 + (Rf/Rin) |
An inverting amplifier connects the input to the negative terminal and flips the output signal by 180 degrees. A non-inverting amplifier connects the input to the positive terminal and amplifies the signal without changing its phase (0 degrees).
