24-Bit, Multi-Standard, Stereo D/A Converter

The CS4397 is a complete, high-performance, 24-bit 48/96/192 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. This multi-bit architecture features significantly lower out-of-band noise and jitter sensitivity than traditional 1-bit designs. The advanced DEM guarantees low noise and distortion at all signal levels.

The CS4397 features multi-stand support for DSD and external interpolation filters.
