ADUM3211TRZ-EP-RL7

Overview

The ADUM3211TRZ-EP-RL7 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. The device provides 2500 Vrms isolation voltage and features a common mode transient immunity of at least 25 kV/µs. Packaged in an SOIC-8 surface-mount format, it ensures unidirectional signal transmission with low propagation delay characteristics suitable for high-speed industrial applications.

Feature Summary

• Integrates high-speed CMOS circuitry with on-chip transformer technology for robust magnetic isolation
• Provides two independent bidirectional channels with high common mode transient immunity
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix EP-RL7 against official Analog Devices documentation to confirm military-grade qualification and reel packaging specifications. Ensure compatibility with existing PCB footprints and verify that the 25 Mbps data rate meets system timing requirements before finalizing procurement decisions.

Selection Notes

Select this component when high-speed data transfer exceeding standard 10 Mbps isolators is required alongside strict isolation voltage ratings. Consider the SOIC-8 package constraints and ensure thermal management aligns with the specified operating temperature limits for the intended environment.

Part Context

This part belongs to the ADuM321x family of dual-channel digital isolators. It represents an enhanced performance variant offering higher data throughput compared to lower-speed counterparts in the same series, designed for demanding environments where signal integrity and isolation reliability are critical.

Replacement Considerations

Cross-reference with ADUM3211 variants such as ADUM3211ARZ or ADUM3211TRZ for non-military grade equivalents. Verify functional pinout compatibility and electrical parameter overlaps before substituting.
