ADUM131E1BRZ

Overview

The ADUM131E1BRZ is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000Vrms isolation with a data rate of 150Mbps and 75kV/µs common-mode transient immunity (CMTI). The device features two forward channels and one reverse channel, operating on a 1.8V to 5.5V supply. Key electrical parameters include a maximum propagation delay of 7.2ns, rise/fall times of 2.5ns, and a typical operating current of 8.8mA. It functions within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Robust magnetic coupling architecture for high reliability
• Integrated output enable functionality for power management
• High common-mode transient immunity for noisy environments

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and functional variations. Ensure compatibility with existing PCB footprints and voltage levels. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement decisions.

Selection Notes

Select this component when bidirectional communication is required alongside standard unidirectional paths. The inclusion of an output enable pin allows for dynamic power reduction during idle states. Verify that the 150Mbps speed meets system timing requirements and that the 16-SOIC package fits the design constraints.

Part Context
