DescriptionThe CS4385 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. Features♦ 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 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♦ 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 and Serial Ports
