Working Principles

The TAS5721DCAR utilizes a closed-loop Class-D architecture to amplify the audio signal. It converts the digital audio input into a pulse-width modulated (PWM) signal, which is then amplified by the power stage. The closed-loop operation ensures accurate feedback and control, resulting in improved linearity and reduced distortion.

The advanced modulation scheme employed by the TAS5721DCAR enables high efficiency by minimizing switching losses. This leads to less power dissipation and increased overall system efficiency.
