ADUM5241ARZ

The ADuM524x is a dual-channel digital isolator with integrated isoPower isolated power supply. The die-level DC-DC converter is based on iCoupler technology, delivering up to 50 mW of regulated isolated power at 5 V, eliminating the need for a separate isolated DC-DC converter in low-power isolation designs. iCoupler technology is used to isolate both logic signals and the DC-DC converter, providing a compact, fully isolated solution. The ADuM524x isolator provides two independent isolated channels supporting multiple channel configurations, with an input operating voltage of 5 V. The ADuM524x family can be used in conjunction with other iCoupler products to achieve higher channel counts.
