Working Principles

The PCM1798DBG4 operates by receiving digital audio data through the SDIN pin. The serial clock input (SCLK) synchronizes the data transfer, while the left/right channel clock input (LRCK) determines the channel being processed. The digital audio data is then converted into analog signals using advanced oversampling and filtering techniques. The resulting analog signals are available at the VOUTL and VOUTR pins.

Detailed Application Field Plans

The PCM1798DBG4 is commonly used in the following applications:

1. High-end audio systems
2. Professional audio equipment
3. Digital audio workstations
4. Home theater systems
5. Automotive audio systems
