ADuM642xA Quad-Channel Digital Isolators

Analog Devices Inc. ADuM642xA Quad-Channel Digital Isolators feature an isoPower®, integrated, and isolated DC-to-DC converter. These quad-channel isolators are based on iCoupler® technology that offers regulated and isolated power that meets CISPR 32/EN 55032 Class B limits at a full load. The ADuM642xA isolators eliminate the need for separate, isolated DC-to-DC converters in 500mW isolated designs. These quad-channel digital isolators use iCoupler chip scale transformer technology for isolated logic signals and for the magnetic components of the DC-to-DC converter. This results in a small form factor and a total isolation solution.
