An inverting amplifier is a type of electronic amplifier that produces an output voltage that is inverted and amplified compared to its input voltage. It typically uses an operational amplifier (op-amp) configured with feedback resistors to control the gain. The output voltage is proportional to the negative of the input voltage, meaning that if the input increases, the output decreases. This configuration is widely used in various applications, such as signal processing and audio equipment, due to its ability to provide precise gain control and signal inversion. The inverting amplifier is essential in circuits where phase inversion is required, making it a fundamental component in electronics.
