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 mixing,

selectable fast and slow digital interpolation filters fol-

lowed by an oversampled, multi-bit delta sigma

modulator which includes mismatch shaping technology

that eliminates distortion due to capacitor mismatch. Fol-

lowing this stage is a multi-element switched capacitor

stage and low-pass filter with differential analog outputs.

z Advanced Multi-bit Delta Sigma Architecture

z 24-Bit Conversion

z Automatic Detection of Sample Rates up to

192 kHz

z 114 dB Dynamic Range

z -100 dB THD+N

z 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 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

z Compatible with Industry-standard Time

Division Multiplexed (TDM) Serial Interface

z Selectable Digital Filters

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

Soft Ramp

z Low Clock Jitter Sensitivity

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.

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

z Separate 1.8 to 5 V Logic Supplies for the

Control & Serial Ports
