ADUM2286ARIZ

Overview

The ADUM2286ARIZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology to provide electrical isolation between circuits. It features a 5000 Vrms insulation rating and supports data rates up to 100 Mb/s with a typical propagation delay of 24 ns. The device operates on a supply voltage range of 2.7 V to 5.5 V and draws approximately 800 uA of quiescent current per channel. It is housed in a 16-pin SOIC package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides bidirectional signal transmission with default low output configuration for both channels.
• Utilizes iCoupler magnetic coupling technology for high-speed digital isolation without optical components.
• Offers robust common-mode transient immunity to prevent signal corruption during rapid voltage changes.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics monitoring and control circuits

Procurement Notes

Verify the specific suffix (e.g., ARIZ vs. ARIZ-RL) against your reel or cut-tape requirements. Confirm that the 16-SOIC package dimensions match your PCB footprint. Ensure the 5kV isolation rating meets your system's safety standards. Check for RoHS compliance documentation if required by your manufacturing process.

Selection Notes

Select this component when dual-channel isolation is required with moderate data rates. Consider the 2.7V to 5.5V supply range compatibility with your logic levels. Evaluate the 24ns propagation delay against your timing constraints. Verify that the 125°C maximum operating temperature suits your environmental conditions.

Part Context

This part belongs to the ADuM2286 series of dual-channel digital isolators. It is designed to replace traditional optocouplers in applications demanding higher reliability and lower power consumption. The series offers various packaging and speed options to suit different industrial and commercial needs.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM228x family. Verify if higher speed variants like the ADUM2281 are suitable for faster data rates. Ensure substitute parts maintain the same 5kV isolation rating and SOIC-16 package.
