The ADuM524x1 are dual-channel digital isolators with isoPower®
integrated, isolated power. Based on the Analog Devices, Inc.,
iCoupler® technology, a chip scale dc-to-dc converter provides
up to 50 mW of regulated, isolated power at 5 V, which eliminates
the need for a separate isolated dc-to-dc converter in low power
isolated designs. The Analog Devices chip scale transformer
iCoupler technology is used both for the isolation of the logic
signals as well as for the dc-to-dc converter. The result is a small
form factor, total isolation solution.
The ADuM524x isolators provide two independent isolation
channels in a variety of channel configurations, operating from
a 5 V input supply. ADuM524x units can be used in combination
with other iCoupler products to achieve greater channel counts. 1 06014-002 Integrated isolated dc-to-dc converter
