120 dB, 24-Bit, 192 kHz Stereo D/A Converter with DSD Support

The CS4398 is a complete stereo audio 24-bit/192 kHz digital/analog converter (DAC) system. This D/A system includes digital de-emphasis, half dB step-size volume control, ATAPI channel mixing, selectable fast and slow roll off digital interpolation filters followed by an oversampled multibit Delta-Sigma modulator, which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Following this stage is a multi-element switched capacitor stage and low-pass filter with differential analog outputs.

The CS4398 DAC also has a proprietary Direct Stream Digital (DSD) processor, which allows for volume control and 50 kHz on-chip filtering without an intermediate decimation stage. It also offers an optional path for direct DSD conversion by directly using the multi-element switched capacitor array. The CS4398 accepts PCM (pulse code modulation) data at sample rates from 32 kHz to 200 kHz and DSD audio data, has selectable digital filters, consumes little power and delivers excellent sound quality.

With an extensive feature set, the CS4398 provides an ideal solution for a variety of professional and consumer audio applications, such as universal DVD players, digital mixing consoles, audio/video receivers, outboard converter systems and effects processors.
