ADUM240E0BRIZ

Overview

The ADUM240E0BRIZ is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and a common-mode transient immunity of 75 kV/µs. The device operates within a supply voltage range of 1.7 V to 5.5 V, drawing 11.8 mA of quiescent current. It offers a propagation delay of 7.2 ns and supports an insulation voltage of 5000 Vrms. Packaged in a 16-pin SOIC, it functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Integrates four independent unidirectional signal paths for high-density isolation applications
• Employs on-chip thin-film capacitor technology for reliable magnetic signal transmission
• Provides high common-mode transient immunity to reject noise spikes
• Supports wide operating supply voltage ranges for flexible system integration

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing robust patient safety isolation barriers
• Power metering circuits for accurate energy measurement
• Inverter drives and motor control interfaces

Procurement Notes

Verify the specific suffix 'E0' against the official Analog Devices datasheet to confirm channel configuration and pinout compatibility. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact form factor. Consider the 150 Mb/s data rate limit for signal speed requirements. Evaluate the 5000 Vrms insulation rating against system creepage and clearance needs. Compare power consumption against other isolators if battery life is a critical constraint.

Part Context

This part belongs to the ADuM240 series of digital isolators. It represents a generation of devices replacing older optocouplers by offering smaller size, lower power consumption, and higher reliability. The series is designed for general-purpose isolation in industrial and commercial environments where space and efficiency are prioritized.

Replacement Considerations

Check for direct cross-reference part numbers listed in the Analog Devices product selection guide. Verify that any substitute maintains the same 16-SOIC package and 4-channel configuration. Ensure electrical parameters such as CMTI and propagation delay meet or exceed original specifications.
