The CS4391A is a complete stereo digital-to-analog (D/A) system including digital interpolation, fourth-order delta sigma D/A conversion, digital de-emphasis, volume control, channel mixing and analog filtering. The advantages of this architecture include: ideal differential linearity, no distortion mechanisms due to resistor matching errors; no linearity drift over time and temperature and a high tolerance to clock jitter. The CS4391A accepts PCM (pulse code modulation) data at sample rates from 4 to 192kHz and Direct Stream Digital (DSD) audio data. These features are ideal for DVD and SACD (Super Audio CD) players, audio/video receivers and professional audio systems.
