CS4365

CS4365 114 dB, 192 kHz 6-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 Mode – Non-Decimating Volume Control – On-Chip 50 kHz Filter – Matched PCM and DSD Analog Output Levels  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 The CS4365 is a complete 6-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 CS4365 also has a proprietary 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 CS4365 is available in a 48-pin LQFP package in both Commercial (-40°C to +85°C) and Automotive (-40°C to +105°C) grades. The CDB4365 Customer Dem...
