Description
The CS4352 is a complete stereo digital-to-analog sys-
tem including digital interpolation, fifth-order multi-bit
delta-sigma digital-to-analog conversion, digital de-em-
phasis, analog filtering, and on-chip 2 Vrms line-level
driver. The advantages of this architecture include ideal
differential linearity, no distortion mechanisms due to re-
sistor matching errors, no linearity drift over time and
temperature, high tolerance to clock jitter, and a minimal
set of external components.
The CS4352 is available in a 20-pin TSSOP package in
both Commercial grade (-40°C to +85°C) and Automo-
tive grade (-40°C to +105°C). The CDB4352 Customer
Demonstration Board is also available for device evalu-
ation and implementation suggestions. Please see
“Ordering Information” on page 20 for complete details.
These features are ideal for cost-sensitive, 2-channel
audio systems including video game consoles, DVD
players, A/V receivers, set-top boxes, digital TVs and
DVD Recorders, mini-component systems, and mixing
consoles.
