Working Principles

The UDA1338H/N1,557 is a digital-to-analog converter (DAC) that converts digital audio signals into analog signals. It utilizes a high-resolution 24-bit architecture to accurately reproduce audio with minimal distortion and noise. The DAC operates based on the incoming master clock, bit clock, and left/right clock signals, which synchronize the conversion process. The converted analog audio signals are then available at the OUTL and OUTR pins for further amplification or direct usage.
