The CS4382 is a complete 8-channel digital-to-analog
system including digital interpolation, fifth-order delta-
sigma digital-to-analog conversion, digital de-empha-
sis, 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 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 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 con-
soles, effects processors, and automotive audio
systems.
