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 plete 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 mercial (-40°C to +85°C) and Automotive (-40°C to +105°C) grades. The CDB4365 Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 51 for plete details. The CS4365 accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excellent sound quality. These Features are...
