GENERAL DESCRIPTION
The ADuM220x
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 temper-
ature 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 elimi-
nated with these iCoupler products. Furthermore, iCoupler
devices run at one-tenth to one-sixth the power of optocouplers
at comparable signal data rates.
The ADuM220x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). The ADuM220x 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 ADuM220x 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 ADuM220x 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 ADuM320x or ADuM220x 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.
