ADUM3210WBRZ

Overview

The ADUM3210WBRZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features bidirectional data flow with a data rate of 10 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 7.6 mA. It exhibits a propagation delay of 50 ns and is housed in an SOIC-8 surface-mount package. The component supports an extended operating temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Bidirectional data transmission capability for flexible circuit design
• Robust isolation barrier using proprietary magnetic coupling technology
• High common-mode transient immunity ensuring reliable operation in noisy environments

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems with high-voltage isolation needs
• Medical equipment demanding safe patient isolation barriers

Procurement Notes

Verify the specific suffix WBRZ indicates tube packaging rather than reel configuration when sourcing. Confirm AEC-Q100 automotive qualification status aligns with project requirements. Check moisture sensitivity level handling instructions prior to assembly. Ensure compatibility with existing SOIC-8 footprint designs during procurement planning.

Selection Notes

Select this component for applications requiring bidirectional isolation at 10 Mb/s speeds. Compare against unidirectional variants like ADUM3211 if directionality constraints exist. Evaluate power consumption differences against other series members based on the 7.6 mA typical current draw. Consider the wide temperature range suitability for harsh environment deployments.

Part Context

This part belongs to the ADUM3210 series of dual-channel digital isolators. It shares the SOIC-8 package and magnetic coupling architecture with related models but differs in channel directionality and specific electrical parameters. The series is designed to replace traditional optocouplers in modern interface circuits.

Replacement Considerations

ADUM3211WBRZ serves as a functional substitute for unidirectional applications within the same package family.
