Description

The CS4344 family members are complete, stereo dig-

ital-to-analog output systems including interpolation,

multi-bit D/A conversion and output analog filtering in a

10-pin package. The CS4344/5/6/8 support all major

audio data interface formats, and the individual devices

differ only in the supported interface format.

The CS4344 family is based on a fourth order multi-bit

delta-sigma modulator with a linear analog low-pass fil-

ter. This family also includes auto-speed mode

detection using both sample rate and master clock ratio

as a method of auto-selecting sampling rates between

2 kHz and 200 kHz.

The CS4344 family contains on-chip digital de-empha-

sis, operates from a single +3.3 V or +5 V power supply,

and requires minimal support circuitry. These features

are ideal for DVD players & recorders, digital televi-

sions, home theater and set top box products, and

automotive audio systems.

The CS4344 family is available in a 10-pin TSSOP

package in both Commercial (-10 to +85 °C) and Auto-

motive grades (-40 to +85 °C). Please see
