ADUM3210TRZ-EP

Overview

The ADUM3210TRZ-EP is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mbps with a typical propagation delay of 50 ns. The device provides 2500 Vrms isolation voltage and 25 kV/µs common-mode transient immunity. It features unidirectional signal transmission in an 8-pin SOIC package. The enhanced product variant ensures controlled manufacturing baseline and military temperature range operation from -55°C to +125°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip transformer technology for robust magnetic isolation
• Provides enhanced system-level ESD reliability compared to traditional optocoupler alternatives
• Features controlled manufacturing baseline and enhanced product change notification protocols

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Military-grade electronic interfaces demanding extended temperature stability

Procurement Notes

Verify the specific suffix EP indicates the enhanced product variant with controlled manufacturing baseline and military temperature range specifications. Confirm the package type matches the required SOIC-8 footprint. Ensure the datasheet version aligns with the latest Analog Devices documentation for accurate electrical characteristics and pin configurations before finalizing procurement orders.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional channels. Consider the 25 Mbps data rate capability for high-speed applications. Evaluate the 2500 Vrms isolation rating against system safety requirements. The enhanced product designation suggests suitability for environments requiring stricter quality control and wider thermal operating ranges than standard commercial variants.

Part Context

This part belongs to the ADuM3210 series of dual-channel digital isolators. It represents the enhanced product (EP) version, which distinguishes itself through controlled manufacturing processes and extended temperature performance. The series leverages Analog Devices' proprietary iCoupler technology to replace conventional optocouplers in modern interface designs.

Replacement Considerations

Standard ADUM3210TRZ serves as the commercial equivalent but lacks the enhanced product controls and military temperature range. Verify if the non-EP version meets the specific thermal and reliability requirements of the target application before substitution.
