DAC 2-CH Delta-Sigma 18-bit 8-Pin SOIC

The CS4331 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 CS4331 is based on deltasigma modulation, where the modulator output controls the reference voltage input to an ultra-linear analog lowpass 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 CS4331 contain on-chip digital 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 forportable CD players and other portable playback systems.
