ADUM231D0BRIZ

Overview

The ADUM231D0BRIZ is a triple-channel digital isolator utilizing magnetic coupling technology. It provides 5000Vrms isolation voltage with a data rate of 150Mbps. The device features a 2:1 channel configuration (two inputs on one side, one output on the other) and operates unidirectionally. Electrical specifications include a maximum propagation delay of 13ns and a typical rise/fall time of 2.5ns. It functions within a supply voltage range of 1.7V to 5.5V and supports an operating temperature range from -40°C to +125°C. The component is housed in a 16-SOIC package.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides robust 5000Vrms isolation capability for high-voltage noise immunity.
• Supports high-speed data communication at rates up to 150Mbps.
• Operates reliably across extended industrial temperature ranges.

Applications

• Industrial automation systems requiring galvanic isolation
