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
for complete details.
