CS4331

CS4330 CS4331 CS4333 8-Pin Stereo D/A Converter for Digital Audio Features General Description The CS4330, CS4331 and CS4333 are complete, stereo digital-to-analog output systems including interpolation, 1-bit D/A conversion and output analog filtering in an 8-pin package. These devices differ in the serial interface format used to input audio data. The CS4330, CS4331 and CS4333 are 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 2 kHz and 50 kHz while maintaining linear phase response simply by changing the master clock frequency. The CS4330, CS4331 and CS4333 contain on-chip digital de-emphasis, operate from a single +3V or +5V power supply, and consume only 60 mW of power with a 3V power supply. These features make them ideal for portable CD players and other portable playback systems. ORDERING INFORMATION: See page 21.
