    What does an audio amplifier do?

    An audio amplifier improves sound quality. Connect your audio input, adjust the settings, and output the enhanced audio. Audio amplifiers have features for different needs.

    Audio amplifier ICs are designed to boost audio signals to power levels that can drive devices like headphones or speakers. These ICs often have features like mute inputs, volume control, and anti-pop (depop) functions, which set them apart from general-purpose amplifiers. They come in all shapes and sizes, with different amplifier classes, including Class A, Class D, and Class G. Some even have extra features like analog-to-digital conversion along with amplification.

    Working Principle of an Audio Amplifier

    An audio amplifier's power amplification circuit is its heart. It amplifies low-level, low-power audio signals using semiconductor components in the output stage to generate a higher output power. An audio amplifier's key performance metrics include amplification gain, output power, frequency response, distortion, and signal-to-noise ratio.

    Purpose of an Audio Amplifier

    An audio amplifier's main function is to boost the power output of an audio system, increasing volume and clarity. It amplifies the input signal to drive speakers or headphones and allows adjustments in aspects like volume and frequency response.
