D/A Converters CS4397

The CS4397 features multi-standard support for PCM (pulse code modulation), Direct Stream Digital (DSD), and external interpolation filters

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 is a complete high-performance 24-bit, 48/96/192 kHz stereo digital-to-analog (D/A) conversion system. The device includes a digital interpolation filter followed by an 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 D/A converter/low-pass filter with fully differential outputs.
