ADUM2286ARIZ-RL

Overview

The ADUM2286ARIZ-RL is a dual-channel digital isolator from Analog Devices, housed in a SOIC-16 surface-mount package. It provides galvanic isolation via magnetic coupling with an insulation voltage of 5000 Vrms. The device supports bidirectional data transmission at speeds up to 100 Mb/s. Operating parameters include a supply voltage range of 2.7 V to 5.5 V and a typical quiescent current of 800 uA. Key timing specifications feature a propagation delay of 24 ns, with rise and fall times typically at 3 ns. Pulse width distortion is specified at 1000 ns. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture supporting independent signal isolation
• Magnetic coupling technology for high-voltage galvanic separation
• Default low output configuration for defined logic states

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing patient safety isolation barriers
• Power management circuits involving ground potential differences

Procurement Notes

Verify the specific suffix 'RL' against official Analog Devices documentation to confirm reel packaging requirements. Ensure compatibility with standard SOIC-16 footprint designs. Confirm that the default low output polarity aligns with system logic requirements before integration. Check for moisture sensitivity levels if storage conditions are critical.

Selection Notes

Select this component when dual-channel isolation with magnetic coupling is required. Consider the 5000 Vrms insulation rating for high-noise environments. Evaluate the 100 Mb/s data rate against system bandwidth needs. Verify that the 2.7 V to 5.5 V supply range matches available power rails.

Part Context

This part belongs to the ADuM2286 series of dual-channel digital isolators. It utilizes Analog Devices' iCoupler technology for signal transmission across isolation barriers. The series is designed for applications demanding robust performance in electrically noisy environments while maintaining compact form factors.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may not match the specific magnetic coupling characteristics or insulation ratings.
