Description
The CS4382A is a complete 8-channel digital-to-analog
system. This D/A system includes digital de-emphasis,
1 dB step size volume control, ATAPI channel mixing,
selectable fast and slow digital interpolation filters fol-
lowed
by
an
oversampled,
multi-bit
delta-sigma
modulator which includes mismatch shaping technolo-
gy 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 (-40°C to
+85°C) and Automotive grades (-40°C to +105°C). The
CDB4382A Customer Demonstration board is also
available for device evaluation and implementation sug-
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,
digital
TV’s,
mixing
consoles,
effects
processors,
sound
cards,
and
automotive
audio
systems.
