GENERAL DESCRIPTION
The ADuM2210/ADuM22111 are 2-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 that are superior to alternatives such as optocoupler
devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with optocouplers.

Typical optocoupler concerns regarding uncertain current
transfer ratios, nonlinear transfer functions, and 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 run at
one-tenth to one-sixth the power of optocouplers at comparable
signal data rates.
The ADuM2210/ADuM2211 isolators provide two independent
isolation channels in a variety of channel configurations and
data rates (see the Ordering Guide). They operate with the
supply voltage of either side ranging from 3.0 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling voltage
translation functionality across the isolation barrier. The
ADuM2210W and ADuM2211W are automotive grade versions.
Similar to the ADuM3200/ADuM3201 isolators, the ADuM2210/
ADuM2211 isolators contain various circuit and layout
enhancements to provide increased capability relative to system-
level IEC 61000-4-x testing (ESD, burst, and surge). The precise
capability in these tests for either the ADuM3200/ ADuM3201 or
ADuM2210/ADuM2211 products is strongly determined by the
design and layout of the user’s board or module. For more
information, see the AN-793 Application Note, ESD/Latch-Up
Considerations with iCoupler Isolation Products.
