Working Principles

The MAX9760EUI+T is a mono Class D audio amplifier that utilizes pulse-width modulation (PWM) techniques to deliver high-quality audio amplification with minimal power loss. It operates by rapidly switching the input audio signal on and off, using a pair of complementary MOSFETs as the power stage. This allows for efficient power conversion and minimizes heat dissipation.

The amplifier's control circuitry ensures accurate reproduction of the input audio signal while providing protection against short circuits and thermal overload. The integrated shutdown mode allows for power-saving when the amplifier is not in use.
