General Description
The CS4328 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4328 includes an 8×digital interpolation filter followed by a 64×oversampled delta-sigma modulator. 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 1 kHz and 50 kHz while maintaining linear phase response simply by changing the masterclock frequency.
