GENERAL DESCRIPTION
The ADuM131x1 are 3-channel digital isolators based on
Analog Devices, Inc. iCoupler® technology. Combining high
speed CMOS and monolithic air core transformer technology,
these isolation components provide outstanding performance
characteristics superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with optocou-
plers. The typical optocoupler concerns regarding uncertain
current transfer ratios, maximum operating temperature, and
lifetime effects are eliminated with the simple iCoupler digital
interfaces and stable performance characteristics. The need for
external drivers and other discrete components is eliminated
with these iCoupler products. Furthermore, iCoupler devices
consume one-tenth to one-sixth the power of optocouplers at
comparable signal data rates. The iCoupler also offers higher

channel densities and more options for channel directionality.
The ADuM131x isolators provide three independent isolation
channels in a variety of channel configurations and data rates
up to 10 Mbps (see the Ordering Guide). All models operate
with the supply voltage on either side ranging from 2.7 V to
5.5 V, providing compatibility with lower voltage systems as well
as enabling voltage translation functionality across the isolation
barrier. All products allow the user to predetermine the default
output state in the absence of input VDD1 power with a simple
control pin. Unlike other optocoupler alternatives, the ADuM131x
isolators have a patented refresh feature that ensures dc correctness
in the absence of input logic transitions and during power-up/
power-down conditions.
