ADUM4401BRWZ

Overview

The ADUM4401BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a data rate of 10Mbps and 25kV/µs common-mode transient immunity. The device operates on a single power supply ranging from 2.7V to 5.5V, supporting unidirectional signal transmission across four channels. It features low propagation delay and is housed in a 16-lead SOIC package.

Feature Summary

• Quad-channel architecture for multi-signal isolation
• High common-mode transient immunity capability
• Low power consumption design
• Integrated on-chip transformer technology

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power metering applications
• Inverter gate drive circuits

Procurement Notes

Verify the specific suffix (e.g., BRWZ vs. BRIZ) against the datasheet to confirm package type and temperature range. Confirm availability status as distribution may vary. Ensure ESD protection measures are implemented during handling. Validate RoHS compliance documentation prior to integration.

Selection Notes

Select this component when high channel density and robust isolation are required. Compare CMTI ratings against noise environments. Verify supply voltage compatibility with system logic levels. Consider thermal performance within the SOIC-16 footprint constraints.

Part Context

Part of the ADuM440x family of digital isolators. Shares core iCoupler technology with variants offering different channel counts or pinouts. Designed for general-purpose isolation tasks requiring reliable signal transfer across galvanic barriers.

Replacement Considerations

Check ADUM4401BRIZ for tape-and-reel packaging differences. Evaluate ADUM4400 or ADUM4402 for alternative channel configurations. Verify pinout compatibility before substituting.
