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.
Following this stage is a multi-element switched capac-
itor stage and low-pass filter with differential analog
outputs.
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.
The CS4385 is available in a 48-pin LQFP package in
both Commercial (-40°C to +85°C) and Automotive
(-40°C to +105°C) grades. The CDB4385 Customer
Demonstration board is also available for device evalu-
ation and implementation suggestions. Please see
“Ordering Information” on page 54 for complete details.
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
receivers, digital TV’s, mixing consoles, effects proces-
sors, sound cards, and automotive audio systems.

Notes:
4. Current consumption increases with increasing Fs within a given speed mode and is signal dependent.
Max values are based on highest Fs and highest MCLK.
5. ILC measured with no external loading on the SDA pin.
6. Power-Down Mode is defined as RST pin = Low with all clock and data lines held static.
7. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 7 and 8.
