CS4385  
114 dB, 192 kHz 8-Channel D/A Converter  
Features  
Description  
! Advanced Multi-bit Delta Sigma Architecture  
! 24-bit Conversion  
The CS4385 is a complete 8-channel digital-to-analog  
system. This D/A system includes digital de-emphasis,  
half-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 which includes mismatch shaping technology that  
eliminates distortion due to capacitor mismatch. Follow-  
ing this stage is a multi-element switched capacitor  
stage and low-pass filter with differential analog  
outputs.  
! Automatic Detection of Sample Rates up to 192  
kHz  
! 114 dB Dynamic Range  
! -100 dB THD+N  
! Direct Stream Digital Mode  
– Non-Decimating Volume Control  
– On-Chip 50 kHz Filter  
The CS4385 also has a proprietary DSD processor  
which allows for volume control and 50 kHz on-chip fil-  
tering without an intermediate decimation stage. It also  
offers an optional path for direct DSD conversion by di-  
rectly using the multi-element switched capacitor array.  
– Matched PCM and DSD Analog Output  
Levels  
! Compatible with Industry-Standard Time  
Division Multiplexed (TDM) Serial Interface  
The CS4385 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.  
! Selectable Digital Filters  
! Volume Control with 1/2-dB Step Size and Soft  
Ramp  
! Low Clock Jitter Sensitivity  
! +5 V Analog Supply, +2.5 V Digital Supply  
ORDERING INFORMATION  
! Separate 1.8 to 5 V Logic Supplies for the  
Control & Serial Ports  
See page 47.
