CS4385A

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

Features

Description

 Advanced Multi-bit Delta Sigma Architecture

 24-bit Conversion

The CS4385A 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.

 Automatic Detection of Sample Rates up to

192 kHz

 114 dB Dynamic Range

 -100 dB THD+N

 Direct Stream Digital^®(DSD) Mode

–

Non-decimating Volume Control

On-chip 50 kHz Filter

The CS4385A also has a proprietary DSD processor

that allows for volume control and 50 kHz on-chip filter-

ing 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 in

both Hardware and Software Modes

The CS4385A is available in a 48-pin LQFP package in

both Commercial (-40°C to +85°C) and Automotive

(-40°C to +105°C) grades. Please see “Ordering Infor-

mation” on page 53 for complete details.

 Selectable Digital Filters

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

Ramp

The CS4385A accepts PCM data at sample rates from

4 kHz to 216 kHz, Direct Stream Digital audio data, and

delivers excellent sound quality. These features are ide-

al for multi-channel audio systems, including SACD

players, A/V receivers, digital TV’s, mixing consoles, ef-

fects processors, sound cards, and automotive audio

systems.

 Low Clock-jitter Sensitivity

 +5 V Analog Supply, +2.5 V Digital Supply

 Separate 1.8 to 5 V Logic Supplies for the

Control & Serial Ports
