Working Principles

PCM1733U/2KG4 is a digital-to-analog converter that converts digital audio signals into analog signals. It utilizes a 16-bit resolution to accurately represent the audio data. The device operates by receiving digital audio data through the serial audio data input (SDATA) pin. The master clock (MCLK) synchronizes the conversion process, while the frame synchronization (FS) input determines the start and end of each audio frame.

The PCM1733U/2KG4 then processes the digital audio data and generates corresponding analog outputs on channels A (OUTA) and B (OUTB). These analog outputs can be connected to amplifiers or other audio devices for further processing or playback.
