ADUM140E0BRWZ-RL

Overview

The ADUM140E0BRWZ-RL is a general-purpose digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and a maximum propagation delay of 14 ns. The device offers 3750 Vrms isolation voltage and 75 kV/µs common-mode transient immunity (CMTI). Operating on a supply voltage range of 1.7 V to 5.5 V, it is housed in a 16-SOIC package with a width of 7.50 mm.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal isolation
• Provides high common-mode transient immunity of 75 kV/µs
• Supports data rates up to 150 Mbps with low propagation delay
• Features four unidirectional channels in a single package

Applications

• High-speed isolated communication interfaces
• Industrial automation systems requiring galvanic isolation
• Medical equipment with safety isolation requirements
• Power management circuits with feedback isolation

Procurement Notes

Verify the specific suffix 'WZ-RL' confirms the 16-SOIC wide body package and reel packaging format. Ensure compatibility with the required isolation voltage ratings and operating temperature range for your specific application environment. Cross-reference the datasheet for moisture sensitivity level and handling precautions during assembly.

Selection Notes

Select this component when high CMTI and unidirectional isolation are required for quad-channel applications. Consider the 16-SOIC footprint constraints and the 1.7 V to 5.5 V supply range. Evaluate the 150 Mbps speed against system timing requirements and ensure thermal dissipation fits within the 125°C maximum junction temperature limit.

Part Context

This part belongs to the ADUM140E series of robust quad-channel digital isolators. It shares architectural similarities with other iCoupler devices but is distinguished by its specific channel configuration and isolation ratings. The series is designed for applications demanding reliable signal transmission across isolation barriers in noisy environments.

Replacement Considerations

Direct substitutes include ADUM140E0BRZ and ADUM140E0BRQZ, noting differences in package type (SOIC vs QSOP) and tape/reel availability. Verify pinout compatibility and electrical specifications before substitution.
