GENERAL DESCRIPTION

The ADuM5410/ADuM5411/ADuM54121 are quad-channel

digital isolators with isoPower®, integrated, isolated dc-to-dc

converters. Based on the Analog Devices, Inc., iCoupler®

technology, the dc-to-dc converters provide regulated, isolated

power that is adjustable between 3.15 V and 5.25 V. Popular

voltage combinations and the associated power levels are shown

in Table 1.

The ADuM5410/ADuM5411/ADuM5412 eliminate the need

for a separate, isolated dc-to-dc converter in low power, isolated

designs. The iCoupler chip scale transformer technology is used for

isolated logic signals and for the magnetic components of the

dc-to-dc converters. The result is a small form factor, total

isolation solution.

The ADuM5410/ADuM5411/ADuM5412 isolators provide four

independent isolation channels in a variety of channel configura-

tions and data rates (see the Ordering Guide for more

information).
