CS4382A  
114 dB, 192 kHz 8-Channel D/A Converter  
Features  
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.  
! Advanced Multi-bit Delta Sigma Architecture  
! 24-bit Conversion  
! Up to 192 kHz Sample Rates  
! 114 dB Dynamic Range  
! -100 dB THD+N  
! Direct Stream Digital Mode  
! On-Chip 50 kHz Filter  
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.  
! Matched PCM and DSD Analog Output Levels  
! Selectable Digital Filters  
! Volume Control with 1-dB Step Size and Soft  
Ramp  
! Low Clock-Jitter Sensitivity  
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.  
! +5 V Analog Supply, +2.5 V Digital Supply  
! Separate 1.8 to 5 V Logic Supplies for the  
Control & Serial Ports
