ADUM1280WARZ

Overview

The ADUM1280WARZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated insulation voltage of 3000 Vrms and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 3.135 V to 5.5 V and features a propagation delay of 35 ns. Designed for surface-mount installation, it is housed in an SOIC-8 package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional signal transmission capability for flexible circuit design
• High-speed data isolation supporting rates up to 100 Mb/s
• Robust magnetic coupling technology ensuring high common-mode transient immunity

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power management interface circuits

Procurement Notes

Verify the specific suffix WARZ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Confirm current availability status as distribution channels may indicate limited supply or discontinuation. Ensure compliance with RoHS directives and check for any recent product change notices affecting specifications or manufacturing sites before finalizing procurement orders.

Selection Notes

Select this component when bidirectional communication is required at speeds up to 100 Mb/s with 3000 Vrms isolation. Compare power consumption against unidirectional variants if lower current draw is critical. Validate that the SOIC-8 footprint matches the PCB layout constraints. Ensure the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the ADUM1280 series of small, low-power digital isolators. It shares the iCoupler architecture with other family members but differs in channel directionality and speed capabilities. The WARZ suffix typically denotes a specific reel-based packaging format intended for automated surface-mount assembly processes.
