ADUM5211ARSZ

ADUM5211ARSZ Description

The ADUM5211ARSZ from Analog Devices Inc. is a high-performance, dual-channel digital isolator integrating IsoPower® and iCoupler® technologies. Designed for general-purpose isolation, it provides 2500Vrms reinforced isolation with magnetic coupling, ensuring reliable signal transmission in noisy environments. Operating from 2.7V to 5.5V, it supports 1Mbps data rates with low propagation delay (50ns max) and minimal pulse width distortion (10ns max). Its 25kV/µs common-mode transient immunity (CMTI) makes it robust against high-voltage transients. The device includes an isolated power supply, eliminating the need for an external DC-DC converter in many applications. Packaged in a 20-lead SSOP, it is RoHS3 compliant and suitable for surface-mount assembly.
