CS4382A

CS4382A 114 dB, 192 kHz 8-Channel D/A Converter Features  Advanced Multi-bit Delta Sigma Architecture  24-bit Conversion  Up to 192 kHz Sample Rates  114 dB Dynamic Range  -100 dB THD+N  Direct Stream Digital® (DSD™) Mode  On-chip 50 kHz Filter  Matched PCM and DSD Analog Output Levels  Selectable Digital Filters  Volume Control with 1 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 Description The CS4382A is a complete 8-channel digital-to-analog system. This D/A system includes digital de-emphasis, 1 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 CS4382A also has a proprietary DSD processor which allows for 50 kHz on-chip filtering without an intermediate decimation stage. The CS4382A is available in a 48-pin LQFP package in both Commercial (-40°C to +85°C) and Automotive grades (-40°C to +105°C). The CDB4382A Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 48 for complete details. The CS4382A accepts PCM data at sa...
