ADUM2201ARIZ

Digital Isolators Overview

The ADUM2201ARIZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic with monolithic air-core transformers. It provides electrical isolation for bidirectional data transmission across two independent channels. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mb/s. Key electrical specifications include a maximum propagation delay of 150 ns, a common-mode transient immunity of 25 kV/µs, and an insulation voltage rating of 5000 Vrms. It functions reliably in temperatures from -40°C to +125°C.
