TheADuM5410/ADuM5411/ADuM5412are quad-channel digital isolators withisoPower®, 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.The ADuM5410/ADuM5411/ADuM5412 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. TheiCoupler 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 configurations and data rates (see the Ordering Guide for more information).ApplicationsRS-232 transceiversPower supply startup bias and gate drivesIsolated sensor interfacesIndustrial PLCs
