Description
The CS4353 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 V
RMS
line-level
driver from a 3.3 V supply.
The advantages of this architecture include ideal differ-
ential linearity, no distortion mechanisms due to resistor
matching errors, no linearity drift over time and temper-
ature, high tolerance to clock jitter, and a minimal set of
external components.
The CS4353 is available in a 24-pin QFN package in
Commercial (-40°C to +85°C) grade. The CDB4353
Customer Demonstration Board is also available for de-
vice evaluation and implementation suggestions.
Please see
“Ordering Information” on page 25 for com-
plete details.
These features are ideal for cost-sensitive, 2-channel
audio systems including video game consoles, DVD
players and recorders, A/V receivers, set-top boxes,
digital TVs, mini-component systems, and mixing
consoles.
