ADUM241E1BRIZ-RL

Overview

The ADUM241E1BRIZ-RL is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three forward and one reverse unidirectional path. The device supports data rates up to 150 Mb/s and offers an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 7.2 ns, a common-mode transient immunity of 75 kV/µs, and a supply voltage range of 1.7V to 5.5V. It operates within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic coupling technology for high reliability.
• Provides high common-mode transient immunity to withstand rapid voltage changes across the isolation barrier.
• Supports bidirectional signal transmission through a specific 3:1 channel architecture optimized for general-purpose applications.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices
• Medical equipment interfaces needing certified isolation barriers for patient safety
• Power electronics control circuits isolating gate drivers from low-voltage logic

Procurement Notes

Verify the exact suffix BRIZ-RL against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if used in vehicle applications. Cross-reference the part number with official Analog Devices documentation to avoid confusion with similar variants like ADUM241D1BRWZ or non-reel versions.

Selection Notes

Select this component when a quad-channel isolator with high CMTI is required for space-constrained designs. The 16-SOIC package offers a compact footprint suitable for surface-mount assembly. Consider the 1.7V to 5.5V supply range for flexibility in interfacing with various logic families. Verify that the 150 Mb/s data rate meets the system's timing requirements.

Part Context

This part belongs to the ADuM241E series of robust digital isolators. It is designed to replace traditional optocouplers in many applications, offering superior performance in speed, power consumption, and size. The E-series designation typically indicates enhanced reliability or specific automotive-grade qualifications compared to standard industrial variants.

Replacement Considerations

Publicly confirmed substitute part numbers include ADUM241D1BRWZ and ADUM241E0BRIZ. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in packaging or reel specifications that might affect automated assembly processes.
