Working Principles

The SSM3582BCPZ is a Class-D audio amplifier that utilizes pulse-width modulation (PWM) techniques to amplify audio signals efficiently. It converts the input analog audio signal into a digital PWM signal, which is then amplified by the output stage to drive the connected speaker or load.

The amplifier operates by rapidly switching the output stage transistors on and off, controlling the duty cycle of the PWM signal. This allows for efficient power delivery to the load, minimizing power loss and heat generation.
