Overview
The ADUM5242ARZ is a dual-channel digital isolator produced by Analog Devices Inc., featuring integrated isolated power through the isoPower® technology. This component is based on Analog Devices' iCoupler® technology, which utilizes a chip-scale transformer for both logic signal isolation and power conversion. The ADUM5242ARZ provides up to 50 mW of regulated, isolated power at 5 V, eliminating the need for a separate isolated DC-to-DC converter in low-power isolated designs. It is designed for high reliability and safety, with certifications from UL, CSA, and VDE, and operates over a wide temperature range up to 105°C.
