CS4385A

CS4385A 114-dB, 192-kHz 8-Channel D/A Converter Features Description  Advanced Multi-bit Delta Sigma Architecture  24-bit Conversion  Automatic Detection of Sample Rates up to 192 kHz  114 dB Dynamic Range  -100 dB THD+N  Direct Stream Digital® (DSD) Mode – Non-decimating Volume Control – On-chip 50 kHz Filter – Matched PCM and DSD Analog Output Levels  Compatible with Industry-standard Time Division Multiplexed (TDM) Serial Interface in both Hardware and Software Modes  Selectable Digital Filters  Volume Control with 1/2 dB Step Size and Soft Ramp  Low Clock-jitter Sensitivity  +5 V Analog Supply, +2.5 V Digital Supply  Separate 1.8 to 5 V Logic Supplies for the Control & Serial Ports The CS4385A is a complete 8-channel digital-to-analog system. This D/A system includes digital de-emphasis, half-dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters followed by an oversampled, multi-bit 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 CS4385A also has a proprietary DSD processor that 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 CS4385A is availa...
