ADUM231E0BRWZ

Overview

The ADUM231E0BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides robust isolation with 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 range of 2.25 V to 5.5 V, it draws approximately 8.8 mA per channel. Packaged in a 16-lead SOIC_W, it functions unidirectionally across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Robust iCoupler magnetic coupling ensures safe system performance in noisy environments
• High common-mode transient immunity for reliable signal transmission
• Low propagation delay supports high-speed data communication
• Single-supply operation simplifies interface design

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing patient safety isolation
• Power management circuits with isolated feedback loops
• Instrumentation interfaces in harsh electromagnetic environments

Procurement Notes

Verify the specific suffix 'E0' against the official Analog Devices datasheet to confirm channel configuration and isolation ratings. Ensure the SOIC_W package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when high reliability and noise immunity are critical. The 5000 Vrms rating suits applications demanding strong galvanic separation. Consider the 150 Mb/s speed limit for bandwidth requirements. The 16-pin SOIC_W package offers a compact solution for space-constrained designs compared to wider packages.

Part Context

This part belongs to the ADuM231 family of digital isolators. It serves as a replacement for traditional optocouplers in many applications, offering superior performance in speed, power consumption, and size. The family includes variants with different channel counts and isolation levels, all sharing the same core iCoupler technology architecture.

Replacement Considerations

Check pinout compatibility with existing optocoupler designs. Verify that the new propagation delay characteristics meet timing constraints. Ensure the operating voltage range aligns with the target system's logic levels.
