ADUM225N1BRIZ

Overview

The ADUM225N1BRIZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology. It provides robust 5.0 kVrms isolation with an 8.3mm creepage distance. The device features two forward channels and zero reverse channels, supporting data rates up to 150 Mb/s. It operates within a supply voltage range of 1.7 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-lead SOIC, it offers low propagation delay and high common-mode transient immunity for reliable signal transmission.

Feature Summary

• Dual-channel magnetic coupling isolation based on iCoupler technology
• Robust 5.0 kVrms insulation strength with extended 8.3mm creepage clearance
• High-speed bidirectional data transmission capability up to 150 Mb/s
• Wide operating supply voltage range from 1.7 V to 5.5 V

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation barriers
• Power electronics gate drive circuits for motor control
• Instrumentation interfaces demanding high common-mode noise rejection

Procurement Notes

Verify the specific suffix 'BRIZ' against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure compliance with RoHS directives and check for AEC-Q100 qualification if automotive applications are intended. Confirm availability status as distribution may vary by region.

Selection Notes

Select this component when dual-channel isolation is required without reverse feedback paths. The 8.3mm creepage distance suits applications with strict safety clearance requirements. Consider power consumption and thermal dissipation characteristics relative to the 16-lead SOIC package limitations in dense PCB layouts.

Part Context

This part belongs to the ADuM22xN family of dual-channel digital isolators. It shares core iCoupler architecture with variants like ADUM225N0BRIZ but differs in channel directionality and reverse channel configuration. The family emphasizes high reliability and compact form factors for industrial and medical markets.

Replacement Considerations

Direct substitutes include ADUM225N0BRIZ for similar isolation specs with different channel polarity. Cross-reference ADUM226N0WBRIZ for automotive-grade options with reverse channels. Verify pinout compatibility and electrical parameters before substitution.
