Working Principles

The PCM1702P-KG4 operates by converting digital audio signals into analog voltages using a combination of oversampling, filtering, and digital-to-analog conversion techniques. The digital audio data is received through the serial data input (DOUT) pin and synchronized with the bit clock (BCK) and left/right clock (LRCK) inputs. The DAC then converts the digital data into analog voltages, which are output through the respective channel pins (VOUTL+/- and VOUTR+/-).
