GENERAL DESCRIPTION

The ADuM220x1 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 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. In addition, the ADuM220x provide low pulse width

distortion (<3 ns for BRWZ grade) and tight channel-to-

channel matching (<3 ns for BRWZ grade). Unlike other

optocoupler alternatives, the ADuM220x isolators have a

patented refresh feature that ensures dc correctness in the

absence of input logic transitions and during power-up/power-

down conditions.
