ADUM3201WBRZ

Overview

The ADUM3201WBRZ is a bidirectional digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two independent channels with a data rate of 10 Mbps and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 7.7 mA of current. It provides enhanced system-level ESD reliability and meets AEC-Q100 automotive qualification standards. Packaged in an SOIC-8 surface-mount format, it supports a maximum propagation delay of 45 ns and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Bidirectional signal transmission capability for flexible circuit design
• Enhanced system-level electrostatic discharge (ESD) protection
• AEC-Q100 qualified for automotive electronic applications

Applications

• Automotive gate driver isolation
• Industrial communication bus isolation
• Power monitoring systems

Procurement Notes

Verify the specific suffix 'WBRZ' against official documentation to confirm package type and RoHS compliance status. Ensure that the ordering configuration matches the required tape-and-reel or cut-tape specifications. Cross-reference the manufacturer's latest datasheet to validate any recent product change notices or environmental compliance updates before finalizing procurement orders.

Selection Notes

Select this component when bidirectional data transfer is required between isolated domains. The 10 Mbps speed suits moderate-rate interfaces like SPI or I2C. Verify that the 2500 Vrms isolation rating aligns with safety standards. Confirm that the 2.7 V to 5.5 V supply range covers both sides of the isolation barrier. Check if the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ADUM3201 series of digital isolators. It shares the same core architecture as the ADUM3201BRZ but differs in packaging and reel specifications. The series utilizes proprietary iCoupler technology to provide high-speed isolation without optical components. It serves as a robust alternative to traditional optocouplers in modern interface designs.

Replacement Considerations

The ADUM3201BRZ is a confirmed substitute offering identical electrical performance. Verify that the tube packaging of the BRZ variant is compatible with the assembly process. No functional changes are associated with the suffix difference.
