ADUM2285CRIZ

Overview

The ADUM2285CRIZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation with a data rate of 100 Mbps and a common-mode transient immunity of 25 kV/µs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. It features unidirectional signal transmission in a 16-SOIC package, supporting an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates high-speed CMOS and monolithic air-core transformer technology for robust signal isolation
• Provides enhanced safety standards compliance through wide creepage and clearance distances
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power metering applications with high-voltage sensing requirements

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors. Check current availability as distribution channels may report limited stock or discontinuation statuses that differ from official lifecycle notices.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional channels. Ensure the application voltage does not exceed the 5.5 V maximum rating. Consider the 16-SOIC footprint for PCB layout compatibility. Verify that the 100 Mbps speed meets the system timing requirements without necessitating higher-performance alternatives.

Part Context

This part belongs to the ADuM228x family of dual-channel digital isolators. It shares the SOIC-16 package form factor with other variants in the series but differs in channel directionality and default output states. The CRIZ suffix indicates a lead-free, halogen-free RoHS-compliant tube packaging option suitable for surface-mount assembly processes.

Replacement Considerations

Official substitutes include ADUM2281CRIZ and ADUM2283CRIZ. These parts share identical pinouts and electrical specifications but differ in channel directionality configurations. Verify that the alternative's default output state matches the system design requirements before substitution.
