ADUM2285ARIZ-RL

Overview

The ADUM2285ARIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. 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 features bidirectional channel polarity with default low output states. Key electrical parameters include a maximum propagation delay of 24 ns, typical rise and fall times of 3 ns, and an insulation voltage rating of 5000 Vrms. It functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between input and output sides using proprietary magnetic coupling technology.
• Supports bidirectional signal transmission for flexible system design configurations.
• Delivers high common-mode transient immunity to ensure reliable operation in noisy environments.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits for motor drives

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates reel packaging. Check current availability status as supply may be limited. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when bidirectional communication is required alongside high-speed data transfer capabilities. Consider the 16-pin SOIC package constraints and thermal dissipation needs. Evaluate power consumption against system battery life requirements. Compare propagation delay specifications against timing-critical application limits to ensure signal integrity.

Part Context

This part belongs to the ADuM228x series of dual-channel digital isolators. It shares architectural similarities with other iCoupler devices but offers specific speed and configuration options. The series emphasizes compact size and low power consumption compared to traditional transformer-based solutions.

Replacement Considerations

Check for pin-compatible alternatives within the same family that offer different packaging options. Verify if newer revisions maintain identical electrical characteristics. Ensure substitute parts support the required bidirectional functionality and insulation ratings.
