A Class D amplifier module is an electronic device that amplifies audio signals using pulse-width modulation (PWM) or similar techniques to achieve high efficiency. Unlike traditional amplifiers, which continuously amplify signals, Class D amplifiers switch the output devices on and off rapidly, minimizing power loss as heat. This makes them ideal for portable and power-sensitive applications, such as in battery-powered devices and compact sound systems.
