Stereo D/A Converter CS4334 DESCRIPTION The CS4334 family members are complete, stereo digital to analog out put systems including interpolation, 1-bit D/A conversion and out put analog filtering in an 8-pin package. The CS4334 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 voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite adjustment of sample rate between 2kHz and 100kHz simply by changing the master clock frequency. FEATURES *Complete stereo DAC system: Interpolation D/A, Output analog filtering. *24bit Conversion. *96dB dynamic range. *-88dB THD+N *Low clock jitter sensitivity. *Filtered line level outputs *On-Chip digital de-emphasis *Popgaurd technology.
