ADUM2286CRIZ

Overview

The ADUM2286CRIZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology to provide electrical isolation. 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 offers an insulation voltage of 5000 Vrms and features unidirectional signal transmission with default low output polarity. Packaged in a 16-lead SOIC, it ensures reliable performance across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation between circuits using proprietary magnetic coupling architecture.
• Supports high-speed digital communication with data rates reaching 100 Mb/s per channel.
• Features unidirectional signal paths with defined default low output states for predictable initialization.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits demanding high common-mode transient immunity

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check current availability as supply may be restricted. Ensure storage conditions meet humidity sensitivity requirements before assembly.

Selection Notes

Select this part when bidirectional isolation is not required and default low outputs are acceptable. Compare power consumption against ADUM2280 if lower quiescent current is critical. Verify package compatibility with existing PCB footprints. Consider thermal management needs given the SOIC-16 form factor.

Part Context

Part of the ADuM228x family of dual-channel digital isolators. Shares architectural similarities with ADUM2280 but differs in channel directionality and output configuration. Designed for applications requiring moderate speed isolation with standard CMOS logic compatibility.

Replacement Considerations

ADUM2280CRIZ serves as a functional alternative for bidirectional applications. ADUM2286ARIZ offers equivalent specifications with different suffix variations. Verify pinout compatibility and parameter tolerances before substitution.
