GENERAL DESCRIPTION
The ADuM5401/ADuM5402/ADuM5403/ADuM54041 devices
are quad-channel digital isolators with isoPower, an integrated,
isolated dc-to-dc converter. Based on the Analog Devices, Inc.,
iCoupler® technology, the dc-to-dc converter provides up to
500 mW of regulated, isolated power at either 5.0 V from a 5.0 V
input supply or 3.3 V from a 3.3 V supply. This eliminates the need
for a separate, isolated dc-to-dc converter in low power, isolated
designs. The iCoupler chip scale transformer technology is used
to isolate the logic signals and the magnetic components of the
dc-to-dc converter. The result is a small form factor, total isolation
solution.
The ADuM5401/ADuM5402/ADuM5403/ADuM5404 isolators
provide four independent isolation channels in a variety of
channel configurations and data rates (see the Ordering Guide
for more information).
