GENERAL DESCRIPTION

The ADuM140x

Analog Devices, Inc., iCoupler® technology. Combining high

speed CMOS and monolithic air core transformer technology,

these isolation components provide outstanding performance

characteristics 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

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 consume one-tenth to one-sixth of the power

of optocouplers at comparable signal data rates.

The ADuM140x isolators provide four independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide). All models operate with the supply

voltage on 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 ADuM140x provides low pulse width distortion

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

(<2 ns for CRW grade). Unlike other optocoupler alternatives,

the ADuM140x isolators have a patented refresh feature that

ensures dc correctness in the absence of input logic transitions

and when power is not applied to one of the supplies.

Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.

Other patents are pending.
