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.
