Non-inverting Amplifier
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A non-inverting amplifier is an op-amp configuration where the input signal is applied to the non-inverting terminal and the feedback network is connected to the inverting terminal. The output is in phase with the input and the gain is 1 + Rf/Rg.
Example in context
“A non-inverting amplifier offers high input impedance and is often used to buffer voltage sources without inverting the signal.”
“Evirmeyen bir yükseltici yüksek giriş empedansı sunar ve sinyali tersine çevirmeden voltaj kaynaklarını tamponlamak için sıklıkla kullanılır.”
Where engineers use it
The non-inverting amplifier configuration is essential for applications requiring high input impedance and in-phase output. Engineers use it as a voltage buffer, in active filters, and for impedance matching. It is one of the first op-amp circuits taught in analog design.
Synonyms: non-inverting op-amp circuit, non-inverting stage
Antonyms: inverting amplifier
Practice: can you use “Non-inverting Amplifier” at work?
You need to interface a high-impedance piezoelectric sensor (10 MΩ output impedance) to a low-impedance ADC input. Explain why a non-inverting amplifier is preferred and design the gain stage.
Show a model answer
“Choose a non-inverting amplifier when you need a high input impedance buffer.”
