ADUM3201BRZ

Overview

The ADUM3201BRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. 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 provides 2500 Vrms isolation voltage and exhibits a common-mode transient immunity (CMTI) of 25 kV/µs. Key timing parameters include a maximum propagation delay of 50 ns and typical rise/fall times of 2.5 ns. It functions in an unidirectional configuration with a 1/1 channel arrangement, housed in an 8-SOIC package.

Feature Summary

• Integrates two independent signal paths using on-chip miniaturized transformers for galvanic isolation.
• Provides enhanced system-level ESD reliability compared to standard optical couplers.
• Maintains signal integrity through high common-mode transient immunity capabilities.

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal transmission
• Power management circuit monitoring

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging and reel specifications. Ensure compatibility with required operating temperature ranges and voltage levels. Cross-reference part numbers with manufacturer databases to avoid counterfeit components. Confirm RoHS compliance status for regulatory adherence. Validate pinout configurations against the latest datasheet revisions before integration.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional signal flow. Consider the 10 Mb/s data rate limit for high-speed applications. Evaluate the 2500 Vrms isolation barrier for safety requirements. Compare power consumption metrics against alternative isolators if energy efficiency is critical. Ensure the 8-SOIC footprint fits the available PCB space constraints.

Part Context

This device belongs to the ADUM3201 series of digital isolators. It represents a solid-state alternative to traditional optocouplers, offering improved performance in speed and reliability. The series is designed for general-purpose isolation tasks in various electronic systems.

Replacement Considerations

Check for direct substitutes within the ADUM320x family that may offer different channel counts or data rates. Verify pin-to-pin compatibility with existing designs before swapping components. Consult official substitution guides for validated alternatives.
