CS4334/5/6/7/8/9

8-Pin, 24-Bit, 96 kHz Stereo D/A Converter

Features

Complete Stereo DAC System: Interpolation,

Description

The CS4334 family members are complete, stereo digi-

tal-to-analog output systems including interpolation, 1-bit

D/A conversion and output analog filtering in an 8-pin

package. The CS4334/5/6/7/8/9 support all major audio

data interface formats, and the individual devices differ

only in the supported interface format.

The CS4334 family is based on delta-sigma modulation,

where the modulator output controls the reference volt-

age input to an ultra-linear analog low-pass filter. This

architecture allows for infinite adjustment of sample rate

between 2 kHz and 100 kHz simply by changing the

master clock frequency.

The CS4334 family contains on-chip digital de-empha-

sis, operates from a single +5V power supply, and

requires minimal support circuitry. These features are

ideal for set-top boxes, DVD players, SVCD players, and

A/V receivers.
