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.
