CS4382
114 dB, 192 kHz 8-Channel D/A Converter
24-bit Conversion Up to 192 kHz Sample Rates 114 dB Dynamic Range -100 dB THD+N Supports PCM and DSD Data Formats Selectable Digital Filters Volume Control with Soft Ramp
1 dB Step Size Zero Crossing Click-Free Transitions

Dedicated DSD Inputs Low Clock-Jitter Sensitivity Simultaneous Support for Two Synchronous

Sample Rates for DVD Audio uC or Stand-Alone Operation

The CS4382 is a complete 8-channel digital-to-analog system including digital interpolation, fifth-order deltasigma digital-to-analog conversion, digital de-emphasis, volume control and analog filtering. The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature and a high tolerance to clock jitter.
The CS4382 is available in a 48-pin LQFP package in Commercial grade -10°C to +70°C . The CDB4382 Customer Demonstration Board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 42 for complete details.

The CS4382 accepts PCM data at sample rates from 4 kHz to 192 kHz, DSD audio data, and operates over a wide power supply range. These features are ideal for multi-channel audio systems including DVD players, SACD players, A/V receivers, digital TV’s, mixing consoles, effects processors, and automotive audio systems.
