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.
