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
for complete details.
