ADUM3210TRZ

Overview

The ADUM3210TRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic coupling isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mb/s. The device features a propagation delay of 50 ns with typical rise and fall times of 3 ns. It provides an insulation voltage of 2500 Vrms and functions reliably across an operating temperature range of -40°C to +105°C. Packaged in an SOIC-8 surface-mount format, it draws a typical operating supply current of 7.6 mA.

Feature Summary

• Implements iCoupler technology using monolithic transformer coupling for signal transmission without optical components.
• Provides enhanced system-level ESD reliability compared to traditional isolation methods.
• Supports unidirectional data flow with independent channels for flexible circuit design.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing high insulation voltage and safety compliance.
• Power electronics control circuits isolating gate drivers from low-voltage logic.

Procurement Notes

Verify the specific suffix TRZ indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component matches the exact part number to avoid compatibility issues with existing PCB footprints and design specifications.

Selection Notes

Select this component when high-speed data transmission up to 10 Mb/s is required alongside robust electrical isolation. Consider the SOIC-8 package constraints for board space limitations. Evaluate the 2500 Vrms insulation rating against system safety requirements. Compare power consumption characteristics against other isolators if battery life is a critical design parameter.

Part Context

This part belongs to the ADUM3210 series of dual-channel digital isolators. It shares architectural similarities with the ADUM3211 but differs in maximum data rate specifications. The series represents Analog Devices' approach to integrating isolation barriers directly into CMOS processes for improved performance and reduced size.

Replacement Considerations

The ADUM3210ARZ serves as a tube-packaged alternative to the TRZ variant. Verify pinout compatibility before substitution. Cross-reference datasheets for any differences in thermal performance or electrical limits between variants.
