ADUM240E0BRWZ-RL

Overview

The ADUM240E0BRWZ-RL is a general-purpose digital isolator from Analog Devices, featuring four channels with unidirectional signal transmission. It utilizes iCoupler technology for magnetic coupling isolation, providing a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.2 ns. Operating on a single supply voltage between 2.7 V and 5.5 V, it draws a maximum operating current of 11.4 mA. The component is housed in a 16-lead SOIC wide package and functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent unidirectional digital isolators using monolithic air core transformer technology.
• Provides robust noise immunity with high common-mode transient immunity ratings.
• Supports high-speed data transmission up to 150 Mb/s with low propagation delay.
• Operates reliably across extended industrial temperature ranges.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
