CS4396
24-Bit, 192 kHz D/A Converter for Digital Audio
Features
l 24 Bit Conversion
l Up to 192 kHz Sample Rates
l 120 dB Dynamic Range
l -100 dB THD+N
l Advanced Dynamic-Element Matching
l Low Clock Jitter Sensitivity
l Digital De-emphasis for 32 kHz, 44.1 kHz and
48 kHz
l External Reference Input
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.
