ADUM1285ARZ-RL7

Overview

The ADUM1285ARZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 3000 Vrms isolation with a data rate of 1 Mb/s and typical propagation delay of 23 ns. Operating on a single supply voltage between 3.135 V and 5.5 V, it features unidirectional channels with default low output states. The device operates within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Feature Summary

• Integrates two independent unidirectional communication channels for signal isolation
• Employs iCoupler magnetic coupling technology for galvanic isolation
• Includes default low output state configuration for safety-critical applications

Applications

• Industrial automation systems requiring isolated digital communication
• Power electronics control circuits needing high common-mode transient immunity
• Medical equipment interfaces demanding reliable signal isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific reel packaging requirements prior to ordering. Ensure storage conditions meet moisture sensitivity level standards to maintain device integrity during assembly processes.

Selection Notes

Select this component when bidirectional isolation is not required and unidirectional signal transfer suffices. Consider the 3000 Vrms isolation rating for high-voltage separation needs. Evaluate the 1 Mb/s data rate against system timing requirements to ensure adequate performance margins.

Part Context

This part belongs to the ADUM1285 series of digital isolators. It shares the SOIC-8 footprint with other variants but differs in channel directionality and isolation voltage ratings. The RL7 suffix indicates reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Cross-reference with ADUM1285ARZ for tube packaging equivalents. Verify pinout compatibility and electrical parameter alignment before substituting with other iCoupler family members.
