This D/A system includes digital de-emphasis, 1 dB step size volume control, ATAPI channel mixing, selectable fast and slow digital interpolation filters fol- lowed by an oversampled, multi-bit delta-sigma modulator which includes mismatch shaping technolo- gy that eliminates distortion due to capacitor mismatch. Following this stage is a multi-element switched capac- itor 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 in- termediate 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 sug- gestions. Please see “Ordering Information” on page 48 for complete details. The CS4382A accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excel- lent sound quality. These features are ideal for multi- channel audio systems including SACD players, A/V re- ceivers, digital TV’s, mixing consoles, effects processors, sound cards, and automotive audio systems.
