GENERAL DESCRIPTION

The ADuM130x1 are triple-channel digital isolators based on the

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

speed CMOS and monolithic transformer technology, these

isolation components provide outstanding performance

characteristics superior to alternatives, such as optocouplers.

By avoiding the use of LEDs and photodiodes, iCoupler

devices remove the design difficulties commonly associated

with optocouplers. 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 ADuM130x isolators provide three independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide). Both 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 ADuM130x provide 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 ADuM130x 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.
