GENERAL DESCRIPTION

The ADuM3400/ADuM3401/ADuM3402

are 4-channel digital

isolators based on the Analog Devices, Inc., iCoupler® technol-

ogy. Combining high speed CMOS and monolithic air core

transformer technology, these isolation components provide

outstanding performance characteristics superior to alternatives

such as optocoupler devices.

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. Further-

more, iCoupler devices consume one-tenth to one-sixth the

power of optocouplers at comparable signal data rates.

The 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 3.0 V to 5.5 V, providing compatibility with

lower voltage systems as well as enabling a voltage translation

functionality across the isolation barrier. The isolators have a

patented refresh feature that ensures dc correctness in the absence

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

conditions.

In comparison to the ADuM1400/ADuM1401/ADuM1402

isolators, the ADuM3400/ADuM3401/ADuM3402 isolators

contain various circuit and layout changes to provide increased

capability relative to system-level IEC 61000-4-x testing (ESD/

burst/surge). The precise capability in these tests for either set of

isolators is strongly determined by the design and layout of the

user board or module. For more information, see the AN-793

Application Note, ESD/Latch-Up Considerations with iCoupler

Isolation Products.
