GENERAL DESCRIPTION
The ADuM221x1 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 opto-
couplers. 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 ADuM221x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). The ADuM221x models 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 ADuM221x isolators have a patented refresh feature
that ensures dc correctness in the absence of input logic transi-
tions and during power-up/power-down conditions.
Similar to the ADuM320x isolators, the ADuM221x isolators con-
tain 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 ADuM320x or ADuM221x 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.
