    Description

    The CS4382 is a complete 8-channel digital-to-analogsystem including digital interpolation, fifth-order delta-sigma digital-to-analog conversion, digital de-empha-sis, volume control and analog filtering. The advantagesof this architecture include: ideal differential linearity, nodistortion mechanisms due to resistor matching errors,no linearity drift over time and temperature and a hightolerance to clock jitter.

    The CS4382 is available in a 48-pin LQFP package inCommercial grade (-10C to +70C). The CDB4382Customer Demonstration Board is also available for de-vice evaluation and implementation suggestions.Please see Ordering Information on page 42 for com-plete details.

    The CS4382 accepts PCM data at sample rates from4 kHz to 192 kHz, DSD audio data, and operates over awide power supply range. These features are ideal formulti-channel audio systems including DVD players,SACD players, A/V receivers, digital TVs, mixing con-soles, effects processors, and automotive audiosystems.
