ADUM3200WBRZ

Overview

The ADUM3200WBRZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two independent channels with unidirectional signal transmission in an 8-lead SOIC package. The device operates on supply voltages ranging from 3 V to 5.5 V and supports data rates up to 10 Mbps. Key electrical parameters include a maximum propagation delay of 45 ns, an isolation voltage of 2500 Vrms, and a common-mode transient immunity of 25 kV/µs. It is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates CMOS and monolithic air-core transformer technology for high-speed digital isolation
• Provides enhanced system-level ESD reliability across the isolation barrier
• Supports bidirectional voltage translation between different logic levels
• Delivers low dynamic power consumption per channel

Applications

• Industrial fieldbus isolation
• Inverter control circuits
• Power supply feedback loops
• PWM controller signal isolation

Procurement Notes

Verify the specific suffix 'WBRZ' to confirm the wide-body SOIC-8 package configuration and tube packaging format. Confirm that the component meets AEC-Q100 qualification requirements if intended for automotive use. Ensure input specifications align with the 3 V to 5.5 V operating range and check for any regional distribution restrictions or limited availability status before finalizing orders.

Selection Notes

Select this component when unidirectional isolation is required for dual-channel applications. It is suitable for systems needing 2500 Vrms isolation with moderate data rates up to 10 Mbps. Consider the 45 ns propagation delay and 25 kV/µs CMTI for timing-sensitive designs. Compare against other ADUM3200 variants if bidirectional functionality or reel packaging is preferred over tube packaging.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares core architectural similarities with other members like the ADUM3200BRZ but differs in package style and polarity configuration. The series leverages Analog Devices' proprietary iCoupler technology to replace traditional optocouplers, offering improved longevity and performance consistency without LED degradation issues.

Replacement Considerations

ADUM3200BRZ serves as a direct functional substitute within the same family, differing primarily in package type (narrow vs. wide SOIC) and polarity.
