GENERAL DESCRIPTION

The ADuM240x

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. The typical optocoupler concerns regarding uncertain

current transfer ratios, nonlinear transfer functions, and

temperature and lifetime effects are eliminated with the simple

Rev. D

iCoupler digital interfaces and stable performance characteristics.

Furthermore, iCoupler devices run at one-tenth to one-sixth

the power of optocouplers at comparable signal data rates.

The ADuM240x isolators provide four independent isolation

channels in a variety of channel configurations and data rates (see

the Ordering Guide). The ADuM240x models operate with the

supply voltage of either side ranging from 2.7 V to 5.5 V, providing

compatibility with lower voltage systems as well as enabling a

voltage translation functionality across the isolation barrier. In

addition, the ADuM240x provide low pulse width distortion (<2 ns

for CRWZ grade) and tight channel-to-channel matching (<2 ns

for CRWZ grade). The ADuM240x isolators have a patented

refresh feature that ensures dc correctness in the absence of input

logic transitions and during power-up/power-down conditions
