CS4385

114 dB, 192 kHz 8-Channel D/A Converter

Features

Description

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.

Advanced Multi-bit Delta Sigma Architecture

24-bit Conversion

Automatic Detection of Sample Rates up to

192 kHz

114 dB Dynamic Range

-100 dB THD+N

Direct Stream Digital Mode

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.

Non-Decimating Volume Control

On-Chip 50 kHz Filter

Matched PCM and DSD Analog Output

Levels

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.

Compatible with Industry-Standard Time

Division Multiplexed (TDM) Serial Interface

Selectable Digital Filters

Volume Control with 1/2-dB Step Size and Soft

Ramp

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.
