Working Principles
The MAX9776ETJ+TG104 is a stereo audio amplifier that operates in Class D mode. It utilizes pulse-width modulation (PWM) techniques to amplify the audio signal efficiently. The input audio signal is converted into a high-frequency PWM signal, which is then amplified by the power stage of the IC. The amplified PWM signal is then filtered to remove any high-frequency components and provide a clean audio output.
