ADUM5240 Dual-Channel Isolators with isoPower® Integrated DC/DC Converter, 50 mW (2/0 channel directionality)

The ADuM524x are dual-channel digital isolators with isoPower integrated, isolated power. Based on the Analog Devices, Inc. iCoupler® technology, a chip-scale DC/DC converter provides up to 50 mW of regulated, isolated power at 5 V, which eliminates the need for a separate isolated DC/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/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 may be used in combination with other iCoupler products to achieve greater channel counts.
