Working Principles

The MAX9736DETJ+T is a Class D audio amplifier, which uses pulse-width modulation (PWM) to amplify the audio signal. It operates by rapidly switching the power supply voltage on and off to the load (speaker) according to the input audio signal. This switching action allows for high efficiency and low power dissipation.

The amplifier consists of a modulator, output stage, and feedback loop. The modulator converts the analog audio input into a PWM signal. The output stage amplifies the PWM signal and drives the speaker. The feedback loop ensures accurate reproduction of the input signal by comparing the amplified output with the original input and making necessary adjustments.
