ADUM2285BRIZ

Overview

The ADUM2285BRIZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage and supports data rates up to 100Mb/s with a typical propagation delay of 24ns. The device operates on a single supply voltage between 3V and 5.5V, drawing 800uA of quiescent current. It features bidirectional channels in a 16-SOIC package, offering 25kV/µs common-mode transient immunity and a creepage distance of 8.3mm for robust high-voltage isolation.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers without optical components.
• Provides robust 5000Vrms isolation capability suitable for demanding high-voltage environments.
• Features bidirectional channel configuration allowing flexible data flow directionality.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing patient isolation protection
• Power metering applications involving high-voltage sensing

Procurement Notes

Verify the specific suffix 'BRIZ' against official Analog Devices documentation to confirm pinout orientation and output polarity characteristics. Ensure compatibility with the target PCB footprint for the 16-SOIC package. Confirm that the required data rate and isolation voltage meet the system specifications before procurement.

Selection Notes

Select this component when bidirectional communication is required within a dual-channel isolated interface. Compare performance metrics such as propagation delay and power consumption against alternative isolators if low-latency or ultra-low-power operation is critical. Verify thermal management requirements for the SOIC package under maximum operating conditions.

Part Context

This part belongs to the ADUM2285 series of digital isolators, which are designed for general-purpose isolation tasks. The series includes variants with different channel directions and data rates. The ADUM2285BRIZ specifically offers bidirectional channels, distinguishing it from unidirectional counterparts like the ADUM2285CRIZ.

Replacement Considerations

Check for direct substitutes within the ADUM228x family, such as the ADUM2285ARIZ, noting differences in channel directionality. Verify pin-to-pin compatibility with other 16-SOIC digital isolators if cross-referencing with competitors, ensuring isolation ratings match.
