Working Principles

The CS4355-CSZ operates by receiving digital audio data through the serial data input (SDIN) pin. The serial clock input (SCLK) synchronizes the data transfer, while the left/right channel select input (LRCLK) determines the active audio channel. The master clock input (MCLK) provides timing reference for the conversion process.

Once the digital audio data is received, the CS4355-CSZ converts it into analog signals using a high-resolution DAC. The analog outputs are then available at the OUTL and OUTR pins for further processing or direct connection to audio output devices.
