ADUM3210ARZ

Overview

The ADUM3210ARZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology. It provides 2500 Vrms isolation with a data rate of 1 Mb/s and common-mode transient immunity of 25 kV/µs. Operating on a single supply voltage between 3 V and 5.5 V, it features unidirectional signal transmission. Key electrical parameters include a propagation delay of 50 ns, rise/fall times of 3 ns typical, and operating temperatures from -40°C to +105°C.

Feature Summary

• Dual-channel magnetic coupling isolation based on iCoupler technology
• Enhanced system-level ESD reliability for robust signal integrity
• High common-mode transient immunity supporting noisy environments

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing enhanced safety isolation barriers
• Power management circuits for isolated communication interfaces

Procurement Notes

Verify the complete part number including suffixes such as ARZ or BRZ to ensure correct temperature grade and package specifications. Confirm RoHS compliance status through official manufacturer documentation before procurement. Cross-reference datasheet revisions to validate current technical parameters against legacy versions.

Selection Notes

Select this component when dual-channel unidirectional isolation is required at 1 Mb/s speeds. Ensure the 2500 Vrms isolation rating meets circuit safety standards. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Check power supply requirements align with the 3 V to 5.5 V operational range.

Part Context

This device belongs to the ADuM3210 family of digital isolators. It shares the iCoupler architecture with other models in the series but offers specific channel counts and speed ratings. The ARZ suffix indicates a lead-free, halogen-free RoHS-compliant version in an SOIC-8 package.

Replacement Considerations
