ADUM4401BRIZ

Overview

The ADUM4401BRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides 5000 Vrms isolation voltage with an 8 mm creepage distance. Key electrical parameters include a typical propagation delay of 32 ns, rise/fall times of 3 ns, and a maximum pulse width distortion of 100 ns. It functions in unidirectional mode across four channels, housed in a 16-SOIC package, and maintains operation between -40°C and +105°C.

Feature Summary

• Integrates high-speed CMOS circuitry with single-chip air-core transformer technology for signal transmission.
• Provides robust protection against high-voltage transients through 5000 Vrms insulation ratings.
• Supports bidirectional communication capabilities with level translation between 3.3 V and 5 V domains.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing enhanced safety isolation
• Instrumentation interfaces demanding high common-mode transient immunity

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code and lot number against official documentation. Confirm the specific suffix 'BRIZ' matches the required SOIC-16 package and reel/cut-tape specifications. Ensure compliance with RoHS directives as indicated in the datasheet before integration into production lines.

Selection Notes

Select this component when high data throughput up to 90 Mbps is required alongside strong isolation barriers. The 16-SOIC package suits surface-mount applications with limited board space. Consider the 5000 Vrms rating for environments with significant potential differences between ground planes.
