Description

The CS4397 is a complete high performance 24-bit

48/96/192 kHz stereo digital-to-analog conversion sys-

tem. The device includes a digital interpolation filter

followed by a oversampled multi-bit delta-sigma modula-

tor 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 ar-

chitecture 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.
