ADUM225N0BRIZ-RL

Overview

The ADUM225N0BRIZ-RL is a robust dual-channel digital isolator from Analog Devices, utilizing proprietary cMOS technology for magnetic coupling. It provides 5.0 kVrms isolation voltage with an 8.3mm creepage distance. The device features two forward channels and zero reverse channels, operating at data rates up to 150 Mb/s. It supports supply voltages between 1.7 V and 5.5 V, with a typical quiescent current of 5.9 mA per channel. Packaged in SOIC-8 format, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology for signal integrity across potential differences.
• Features a wide operating supply voltage range compatible with various logic families.
• Offers high common-mode transient immunity for reliable operation in noisy environments.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with ground potential differences

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the N0 variant specifies zero reverse channels against designs requiring bidirectional feedback paths. Ensure the SOIC-8 package footprint matches the PCB layout constraints. Check for AEC-Q100 qualification if automotive reliability standards are mandatory for the application environment.

Selection Notes

Select this component when dual unidirectional isolation is required without reverse channel functionality. Compare against variants with reverse channels if bidirectional data flow is necessary. Consider the 8.3mm creepage requirement for safety compliance. Evaluate power consumption against thermal management capabilities in enclosed enclosures.

Part Context

This part belongs to the ADUM225N series of robust digital isolators. It shares the core cMOS isolation architecture with other members but differs in channel configuration. The N0 designation specifically denotes the absence of reverse channels, distinguishing it from N1 or N2 variants that include backward communication paths for status reporting.

FAQ

Does the ADUM225N0BRIZ-RL support bidirectional communication?

No, the N0 suffix indicates zero reverse channels, meaning it only supports unidirectional data transmission from input to output.

What is the maximum data rate for this isolator?

The device supports data rates up to 150 Mb/s for both forward channels.
