The CS4334/35/38/39 family of products are complete stereo audio digital/analog converter (DAC) output systems that include interpolation, 1-bit D/A conversion and output analog filtering in an 8-pin package. These DACs support all major audio data interface formats, and the individual devices differ only in the supported interface format.
These devices are based on Delta-Sigma modulation, in which the modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite adjustment of sample rates between 2 kHz and 100 kHz simply by changing the master clock frequency.
The CS4334/35/38/39 family contains on-chip, digital de-emphasis, operates from a single 5 V power supply and requires minimal support circuitry. These features are ideal for set-top boxes, DVD players, SVCD players and automotive audio systems.
