Working Principles

The PCM1719EG4 is a digital-to-analog converter that utilizes advanced techniques to convert digital audio signals into analog form. It employs a high-resolution architecture capable of handling up to 24-bit resolution and sampling rates of up to 192 kHz. The device operates on a 3.3 V power supply and incorporates a built-in mute control for easy audio management.

The PCM1719EG4 receives serial digital audio data through the SDIN pin and synchronizes it with the clock signal provided via the SCLK pin. The LRCK pin determines whether the incoming data represents the left or right channel. The converted analog audio signals are available at the VOUTL and VOUTR pins for the left and right channels, respectively.
