Product Summary

The CS4390-KS is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4390-KS 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. The CS4390-KS also includes an extremely flexible serial port utilizing mode select pins to support multiple interface formats. The master clock can be either 256, 384, or 512 times the input sample rate, supporting various audio environments.
