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 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.
