ADUM2285BRIZ-RL

Overview

The ADUM2285BRIZ-RL 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 voltage rating and supports data rates up to 100 Mb/s. The device operates with a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 800 uA. Packaged in a 16-pin SOIC, it offers bidirectional signal transmission with a propagation delay of 24 ns.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed digital signal isolation
• Provides robust galvanic isolation with a 5000 Vrms insulation voltage rating
• Supports bidirectional data transmission at speeds up to 100 Mb/s
• Features low power consumption suitable for energy-efficient designs

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power monitoring and control circuits
• Inverter gate drive applications

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required within a single package. Compare against the ADUM2281 series if lower channel counts are sufficient. Verify that the 100 Mb/s data rate meets system timing requirements and that the 5000 Vrms isolation level satisfies safety standards for the intended application environment.

Part Context

This part belongs to the ADUM2285 family of general-purpose digital isolators. It shares the same core architecture as the non-reel variant ADUM2285BRIZ but differs in shipping configuration. The series is designed for applications demanding high reliability and low power consumption in noisy environments.

Replacement Considerations

The ADUM2285BRIZ is the identical functional equivalent without the reel suffix. Cross-reference with ADUM2281ARIZ-RL if only one channel is needed. Verify pin compatibility and isolation ratings before substituting with other manufacturers' offerings.
