Working Principles

The TAS2505IRGET is a class-D audio amplifier that utilizes pulse-width modulation (PWM) to convert the digital audio signal into an amplified analog output. It operates by rapidly switching the output stage transistors on and off, controlling the width of the pulses based on the input audio signal. This allows for efficient power conversion and minimizes heat dissipation.
