Overview
The ADUM5211CRSZ-RL7 is a dual-channel digital isolator produced by Analog Devices Inc. This component integrates the isoPower® technology, which includes an isolated dc-to-dc converter. The device is designed to provide regulated, isolated power adjustable between 3.135V and 5.25V, making it suitable for low-power, isolated designs. It utilizes the iCoupler® chip-scale transformer technology for both isolated logic signals and the magnetic components of the dc-to-dc converter. The ADUM5211CRSZ-RL7 is certified by various regulatory bodies, including UL recognition 2500V rms for 1 minute per UL 1577, CSA Component Acceptance Notice 5A, and VDE certificate of conformity.
