120 dB, 24-Bit, 192 kHz Stereo D/A Converter with DSD Support
The CS4398 is a low power, 120 dB stereo digital/analog converter (DAC) featuring digital de-emphasis, half dB step-size volume control, ATAPI channel mixing, and selectable fast and slow roll off digital interpolation filters. This stage is followed by an over sampled multi-bit Delta Sigma modulator, which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch, and a multi-element switched capacitor stage and low-pass filter with differential analog outputs. A Direct Stream Digital® (DSD) processor allows for volume control and 50 kHz on-chip filtering without an intermediate decimation stage, plus an optional path for direct DSD conversion by directly using the multi-element switched capacitor array. The IC accepts DSD audio and 32 kHz to 200 kHz data sample rates, has selectable digital filters and delivers excellent sound quality.
