ADUM3201CRZ

Overview

The ADUM3201CRZ 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 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity (CMTI) of 25 kV/µs. Key timing parameters include a maximum propagation delay of 45 ns and typical rise/fall times of 2.5 ns. It functions in unidirectional mode with a 1/1 channel configuration, housed in an 8-pin SOIC package.

Feature Summary

• Enhanced system-level ESD reliability compliant with IEC 61000-4-x standards
• High common-mode transient immunity for robust signal integrity
• Low power consumption suitable for energy-efficient designs
• Wide operating temperature range extending to 125°C

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing enhanced safety isolation
• Power metering applications with high-voltage interfaces
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix 'CRZ' to confirm the tube packaging format and RoHS compliance status. Ensure the order matches the exact part number to avoid confusion with reel-packaged variants like ADUM3201CRZ-RL7. Confirm the manufacturer is Analog Devices Inc. and validate the datasheet version against recent PCN updates regarding wafer fab sites or specification changes before finalizing procurement.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional channels. It is appropriate for applications demanding moderate data speeds up to 25 Mbps rather than high-speed interfaces exceeding 100 Mbps. Consider the 8-SOIC package constraints for PCB layout and verify that the 2500 Vrms isolation rating meets the specific safety requirements of the target application environment.

Part Context

This device belongs to the ADuM3201 series of dual-channel digital isolators. It represents Analog Devices' iCoupler technology, which integrates transformer-based isolation on silicon. The series is designed to replace traditional optocouplers, offering superior performance in terms of speed, power efficiency, and consistency while maintaining small form factors suitable for modern electronic designs.

Replacement Considerations
