CS4327 Datasheet PDF - Cirrus Logic

Description
The CS4327 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4327 includes a digital interpolation filter followed by an 128X 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 and 50 kHz while maintaining linear phase response simply by changing the master clock frequency.
