General Description
The CS4330, CS4331 and CS4333 are complete, ste-
reo 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 infi-
nite 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.
