CS4390-KS

DAC 2CH Delta-Sigma 24Bit 20Pin SSOP

Description

The CS4390 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4390 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.
