Working Principles

TAS5122DFD operates on the principle of class D amplification, which utilizes pulse width modulation (PWM) to convert the digital audio signal into a high-frequency square wave. This square wave is then filtered and amplified to produce the final audio output.

The digital audio signal is received through the serial data input (SD) pin and synchronized with the clock signals (SCLK, LRCK, BCK). The internal digital processing circuitry converts the digital audio signal into PWM signals, which are then fed to the power stage for amplification. The amplified audio signals are finally delivered through the left and right channel audio outputs (OUTL, OUTR).
