Description
The CS4382A is a complete 8-channel digital-to-analog
system. This D/A system includes digital de-emphasis,
one-dB step size volume control, ATAPI channel mix-
ing, selectable fast and slow digital interpolation filters
followed by an oversampled, multi-bit delta sigma mod-
ulator whitch includes mismatch shaping technology
that eliminates distortion due to capacitor mismatch.
Following this stage is a multi-element switched capac-
itor stage and low-pass filter with differential analog
outputs.
The CS4382A also has a proprietary DSD processor
which allows for 50 kHz on-chip filtering without an in-
termediate decimation stage. The CS4382A is available
in a 48-pin LQFP package in both Commercial (-10° to
+70°C) and Automotive grades (-40° to +85°C). The
CDB4382A Customer Demonstration board is also
available for device evaluation and implementation sug-
gestions. Please see
“Ordering Information” on page 47
for complete details.
The CS4382A accepts PCM data at sample rates from
4 kHz to 216 kHz, DSD audio data, and delivers excel-
lent sound quality. These features are ideal for multi-
channel audio systems including SACD players, A/V re-
ceivers,
