Features  Advanced Multi-bit Delta Sigma Architecture  24-bit Conversion  Up to 192 k Hz Sample Rates  114 d B Dynamic Range  -100 d B THD+N  Direct Stream Digital® (DSD™) Mode  On-chip 50 k Hz Filter  Matched PCM and DSD Analog Output Levels  Selectable Digital Filters  Volume Control with 1 d B 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 CS4362A is a plete 6-channel digital-to-analog system. This D/A system includes digital de-emphasis, 1 d B 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 CS4362A also has a proprietary DSD processor which allows for 50 k Hz on-chip filtering without an intermediate decimation stage. The CS4362A is available in a 48-pin LQFP package in both mercial (-40°C to +85°C) and Automotive grades (-40°C to +105°C). The CDB4362A Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 48 for plete details. The CS4362A accepts PCM data at sample rates from 4 k Hz to 216 k Hz, DSD audio data, and delivers excellent sound quality. These features are ideal for multichannel audio systems including SACD players, A/V receivers, digital TV’s, mixing consoles, effects processors, sound cards, and automotive audio systems.
