Description
The CS4334 family members are complete, stereo dig-
ital-to-analog output systems including interpolation,
1-bit D/A conversion and output analog filtering in an
8-pin package. The CS4334/5/8/9 support all major au-
dio data interface formats, and the individual devices
differ only in the supported interface format.
The CS4334 family is based on Delta-Sigma modula-
tion, where the modulator output controls the reference
voltage input to an ultra-linear analog low-pass filter.
This architecture allows for infinite adjustment of sam-
ple 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.
