Working Principles

The TPA2001D2PWPR is a Class-D audio power amplifier that utilizes pulse-width modulation (PWM) techniques to amplify the audio signal. It converts the analog input signal into a digital PWM waveform, which is then amplified by switching the power supply on and off rapidly. This switching action reduces power dissipation and increases efficiency.

The amplified PWM signal is then passed through a low-pass filter to remove any high-frequency components and provide a clean audio output. The resulting audio signal is suitable for driving a speaker or headphones.
