ADUM2286BRIZ-RL

Overview

The ADUM2286BRIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an insulation voltage of 5000 Vrms and features bidirectional channels with default low output polarity. Key electrical parameters include a typical propagation delay of 24 ns and rise/fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• Utilizes proprietary magnetic coupling technology for robust signal isolation
• Provides bidirectional data transmission capability for flexible circuit design
• Features default low output polarity configuration for specific logic interfacing

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power metering applications with isolated communication interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the suffix indicates reel packaging. Check current availability status as supply may be limited. Ensure compliance with RoHS directives if required by your region. Validate that the SOIC-16 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when bidirectional isolation is required at 100 Mb/s speeds. Consider the 5000 Vrms insulation rating for high-voltage separation needs. Evaluate the 2.7 V to 5.5 V supply range compatibility with your system logic levels. Assess the thermal performance within the -40°C to +125°C operational window. Compare against other ADuM228x variants if different channel counts or polarities are needed.

Part Context

This part belongs to the ADuM228x series of dual-channel digital isolators. It shares the core magnetic coupling architecture with similar models like the ADUM2281 and ADUM2286ARIZ. The BRIZ suffix typically denotes specific manufacturing lot or packaging variations within the standard SOIC-16 form factor. It serves as a replacement for older capacitive isolation technologies in space-constrained designs.

Replacement Considerations

The ADUM2286ARIZ-RL is a verified substitute within the same series, offering identical functional specifications. Verify that the pinout and package dimensions remain compatible during substitution. Confirm that any differences in manufacturing date codes do not affect long-term reliability requirements.
