Inverting Amplifier
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: An inverting amplifier is an op-amp configuration where the input signal is applied to the inverting terminal through a resistor, with the non-inverting terminal grounded. The output is inverted and amplified according to the ratio of feedback to input resistors.
Example in context
“The inverting amplifier configuration provides a gain of -Rf/Rin and is widely used in active filters and summing circuits.”
“Eviren yükseltici konfigürasyonu -Rf/Rin kazancı sağlar ve aktif filtrelerde ve toplama devrelerinde yaygın olarak kullanılır.”
Where engineers use it
The inverting amplifier is a fundamental building block in analog circuit design. Engineers use it when signal polarity inversion is needed or when a virtual ground is required for summing multiple inputs. It appears in textbooks, app notes, and simulation libraries.
Synonyms: inverting op-amp circuit, inverting stage
Antonyms: non-inverting amplifier
Practice: can you use “Inverting Amplifier” at work?
You need to scale a sensor output from 0 to -5 V to a 0 to 3.3 V ADC input. Design an inverting amplifier stage with appropriate resistor values and explain the signal inversion.
Show a model answer
“Use an inverting amplifier to achieve the desired negative gain.”
