Working Principles

The SRC4184IPAG operates as a class-D audio amplifier. It uses pulse-width modulation (PWM) techniques to amplify the audio signal efficiently. The input audio signal is converted into a high-frequency PWM signal, which is then amplified by the internal power stage. The amplified PWM signal is then filtered to reconstruct the original audio waveform.
