The CS4349 is a complete stereo digital-to-analog system including digital interpolation, 5th-order multi-bit deltasigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The advantages of this architecture include ideal linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, tolerance to clock jitter, and a minimal set of external components. The CS4349 supports all standard digital audio interface formats, including TDM.
