Description
The CS4354 is a complete stereo digital-to-analog sys-
tem including digital interpolation, third-order multi-bit
delta–sigma digital-to-analog conversion, digital de-em-
phasis, analog filtering, and on-chip 2 VRMS line-level
driver from a 5 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.
These features are ideal for cost-sensitive, two-channel
audio systems including video game consoles, Blu-Ray
Disc and DVD players, set-top boxes, digital TVs, and
DAB/DMB devices.
The CS4354 is available in a 14-pin SOIC package in
Commercial (–40°C to +85°C) grade. The CDB4354
Customer Demonstration Board is also available for de-
vice
evaluation
and
implementation
suggestions.
