CS4397-KS Multi-Standard D/A Converter for Digital Audio


CS4397-KS is a Multi-Standard D/A Converter is a complete high performance 24-bit 48/96/196 kHz stereo digital-to-analog conversion system. The device includes a digital interpolation filter followed by a oversampled multi-bit delta-sigma modulator which drives dynamic-element-matching (DEM) selection logic. The output from the DEM block controls the input to a multi-element switched capacitor DAC/low-pass filter, with fully-differential outputs. The multi-bit architecture features significantly lower out-of-band noise and jitter sensitivity than traditional 1-bit designs, and the advanced DEM guarantees low noise and distortion at all signal levels.
