Description
The CS4396 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.
