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 main- taining linear phase response simply by changing the master clock frequency. The CS4330, CS4331 and CS4333 contain on-chip dig- ital de-emphasis, operate from a single +3 V or +5 V power supply, and consume only 60mW of power with a 3 V power supply. These features make them ideal for portable CD players and other portable playback systems. ORDERING INFORMATION See page 21.
