These new Cirrus Logic 8 and 6-channel

digital-to-analog converters provide

precisely what designers need in today's

multichannel audio applications. They

deliver premium analog performance and

sound quality by utilizing low-latency digital

filtering, fifth-order, multi-bit, Delta-Sigma

digital-to-analog conversion, logarithmic

digital-volume control and switched-

capacitor analog filtering. Both ICs use

patented automatic mode selection based

on sample rate detection to support PCM

data at sample rates from 4 kHz to 192

kHz, and a dedicated interface is included

for DSD audio data. Design the CS4385

(8-channel), and CS4365 (6-channel) into

your next-generation home theater

systems, high-performance sound cards,

SACD and DVD players, A/V receivers,

automotive audio systems, mixing

consoles, and effects processors.

For SACD applications, these D/A

converters include a patented Direct

Stream Digital processor, which includes a

volume-control engine that does not

decimate the data stream, thereby

maintaining the native sampling rate of

2.8224 MHz and preserving the integrity of

the SACD data format. Also included is an

on-chip 50 kHz filter that complies with

recommendations in the SACD standards.

Cirrus Logic's techniques for providing

SACD volume control and filtering offers

manufacturers the ability to add SACD at

no additional cost in the analog section of

their products.

Ease of design, a high level of integration,

and a flexible feature set allows

manufacturers to minimize time to market

while maximizing performance and

consumer affordability.
