Working Principles

The TAS2770RJQR utilizes a Class-D amplifier topology, which converts the digital audio input into a pulse-width modulated (PWM) signal. This PWM signal is then amplified and filtered to drive the connected speaker. The Class-D architecture ensures high efficiency by rapidly switching the output stage between fully on and fully off states, minimizing power losses.
