Working Principles

The PCM1748KEG4 operates by receiving digital audio data through the SDIN pin. The serial clock input (SCLK) synchronizes the data transfer. The left/right channel select (LRCK) determines which channel is being processed. The digital audio data is then converted into analog signals using high-quality internal circuitry. The resulting analog audio signals are available at the VOUTL and VOUTR pins.
