Robust 3.75 kV rms Quad-Channel Isolator with Integrated DC-to-DC Converter & 1 Reverse Channel

The ADuM6410/ADuM6411/ADuM6412 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 regulated, isolated power that is adjustable between 3.15 V and 5.25 V.

The ADuM6410/ADuM6411/ADuM6412 eliminate the need for a separate, isolated dc-to-dc converters 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 converter. The result is a small form factor, total isolation solution.

The ADuM6410/ADuM6411/ADuM6412 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information).
