ADUM1280WCRZ

Overview

The ADUM1280WCRZ is a dual-channel digital isolator from the ADUM1280 series, manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 3000 Vrms. The device supports bidirectional data transmission at a maximum data rate of 100 Mb/s. Key electrical parameters include a typical propagation delay of 24 ns and a supply current of 20 mA per channel. It operates within an extended temperature range from -40°C to +125°C and meets AEC-Q100 automotive qualification standards. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Bidirectional signal transmission capability for flexible circuit design
• High-speed data communication support up to 100 Mb/s
• Robust galvanic isolation via magnetic coupling technology
• Automotive-grade reliability certified under AEC-Q100 standards

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems with high-voltage noise environments
• Medical equipment needing patient isolation protection
• Power conversion circuits with gate drive isolation requirements

Procurement Notes

Verify the specific suffix WCRZ-RL7 indicates reel packaging configuration. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Ensure the ordering part number matches the exact bidirectional variant required for the application design specifications.

Selection Notes

Select this component when bidirectional data flow is necessary across the isolation barrier. Compare against unidirectional variants like the ADUM1280BRZ if only single-direction transmission is needed. Consider the higher supply current consumption compared to lower-speed models when designing power budgets for battery-operated systems.

Part Context

This part belongs to the ADUM1280 family of small form-factor digital isolators. It shares the same pinout and footprint as other members of the series but differs in directionality and speed capabilities. The W suffix typically denotes wide-body packaging options suitable for higher creepage distances.

Replacement Considerations

ADUM1280WCRZ-RL7 is the identical reel-packaged version of this component.
