ADUM241E1BRWZ-RL

Overview

The ADUM241E1BRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., 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 Mbps and provides 5000 Vrms isolation voltage. It operates within a supply voltage range of 1.7 V to 5.5 V, drawing 11.4 mA typical supply current. Propagation delay is 7.2 ns, with common-mode transient immunity of 100 kV/µs. It functions between -40°C and +125°C in a 16-pin WSOIC package.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal isolation
• Provides high common-mode transient immunity against noise interference
• Supports unidirectional data transmission across four isolated channels
• Complies with UL safety standards for insulation recognition

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified safety isolation
• Power electronics control circuits
• Instrumentation interfaces

Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the wide-body SOIC-16 package variant. Confirm RoHS compliance status through official documentation. Check for AEC-Q100 qualification if automotive application is intended. Ensure moisture sensitivity level handling procedures are followed during assembly. Validate that the reel packaging matches production requirements.

Selection Notes

Select this component when high isolation voltage and fast data rates are required in a compact footprint. The 3:1 channel split suits applications with asymmetric data flow. Consider the 100 kV/µs CMTI for noisy environments. Compare power consumption against other isolators if battery operation is critical. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the ADuM241E series of robust digital isolators. It shares the core iCoupler architecture with similar models but differs in package and specific electrical ratings. The series is designed for general-purpose isolation in industrial and commercial applications. It complements other ADuM products offering different channel counts or bidirectional capabilities.

Replacement Considerations

ADUM241D1BRWZ is a parameter-equivalent alternative within the same family. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement meets the same isolation voltage and data rate requirements.
