Actual Size

Targeting high-end consumer and professional audio applications,

the latest D/A converter from Cirrus pushes analog performance to

greater levels while defining a new standard for sound quality. The

CS4398 stereo DAC utilizes an advanced, proprietary multi-bit, ∆Σ

modulator with integrated mismatch noise shaping technology to

provide a closed-loop architecture, eliminating the need for dynamic

element matching (DEM) while ensuring premium sound quality by

removing any potential audible artifacts.

For SACD applications, the CS4398 includes a patented Direct

Stream Digital processor that 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’

techniques for providing SACD volume control and filtering offer

manufacturers the ability to add SACD at no additional cost in the

analog section of their products.

The CS4398 offers 24-bit conversion and supports sample rates up

to 192 kHz. Selectable digital filter response, integrated level shifters

for direct interface to logic levels from 1.8 V to 5 V, and a differential

analog output architecture are packaged in a low-profile 28-pin

TSSOP.

With an extensive feature set and unrivaled price/performance, the

CS4398 provides an ideal solution for a variety of professional and

consumer audio applications, such as universal DVD players (SACD

and DVD-Audio support), digital mixing consoles, A/V receivers,

outboard converter systems, and effects processors.
