What the 24-bit stereo DAC does on the board
The PCM1728E/2KG4 is a 24-bit stereo digital-to-analog converter from Texas Instruments' SoundPlus™ series, sampling at 96 kHz — it takes a digital audio stream and reconstructs two analog output channels for line-level playback in consumer or pro-audio gear.
Package and footprint note
Housed in a 28-SSOP (0.209", 5.30 mm width) surface-mount package, the PCM1728E/2KG4 uses the same 28-SSOP footprint as other SoundPlus™ stereo DACs — the board layout is shared across the family, so a single PCB artwork covers multiple BOM options.
