FEATURES
Description
The CS4391A is a complete stereo digital-to-analog system including digital interpolation, fourth-order deltasigma digital-to-analog 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.
