Description

The CS4344 family members (CS4344, CS4345, and

CS4348) are complete, stereo digital-to-analog output

systems including interpolation, multibit D/A conversion

and output analog filtering in a 10-pin package. The

CS4344 family supports major audio data interface for-

mats. Individual devices differ only in the supported

interface format.

The CS4344 family is based on a fourth-order multibit

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

ter. This family also includes autospeed 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 deempha-

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). See Section 8. “Ordering

Information” on page 23 for complete details.
