ADUM4401BRWZ-RL

Overview

The ADUM4401BRWZ-RL is a quad-channel digital isolator manufactured by Analog Devices Inc. It provides 5000 Vrms isolation capability and supports data rates up to 90 Mb/s. The device operates within a supply voltage range of 2.7 V to 5.5 V. It utilizes magnetic coupling technology for signal transmission across the isolation barrier. The component is housed in a 16-pin SOIC package with a width of 7.50 mm, designed for surface mount applications.

Feature Summary

• Provides enhanced electrostatic discharge protection capabilities
• Utilizes capacitive coupling technology for signal isolation
• Supports unidirectional signal transmission across four independent channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power electronics interfaces for noise reduction

Procurement Notes

Verify current availability status as distribution may be limited or restricted. Confirm that the ordering suffix corresponds to the reel packaging format required for production integration. Ensure compatibility with existing PCB footprint specifications before finalizing procurement decisions.

Selection Notes

Select this component when high isolation voltage ratings are critical for system safety. Consider the specific data rate requirements to ensure the 90 Mb/s limit meets application needs. Evaluate power consumption characteristics against available supply rails to confirm efficient operation within the specified voltage range.

Part Context

This part belongs to the ADuM series of digital isolators from Analog Devices. It represents a general-purpose solution for separating noisy digital signals. The BRWZ suffix indicates specific pinout and packaging variations compared to other variants in the family.

Replacement Considerations

Check for direct substitutes within the ADUM4401 family. Verify pin-to-pin compatibility if considering alternative manufacturers. Ensure isolation voltage and data rate specifications meet or exceed original design requirements.
