ADUM140D0BRQZ

Overview

The ADUM140D0BRQZ is a robust quad-channel digital isolator utilizing Analog Devices iCoupler magnetic coupling technology. It provides four unidirectional data channels with zero reverse channels, supporting data rates up to 150Mbps. The device offers 3000Vrms isolation voltage and a common-mode transient immunity of 75kV/µs. Operating on a single supply voltage range of 1.7V to 5.5V, it features a maximum propagation delay of 15ns and operates within an extended temperature range of -40°C to +125°C. The component is housed in a 16-SSOP package.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics
• Provides robust isolation with 3000Vrms voltage rating and high common-mode transient immunity
• Features integrated input disable functionality for enhanced system control and safety

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix 'QZ' indicates the qualified version and SSOP-16 package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact channel configuration (4:0) and unidirectional directionality specified in the official datasheet to avoid functional mismatches.

Selection Notes

Select this component when four isolated unidirectional channels are required with high CMTI performance. The iCoupler technology eliminates the need for external transformer components, reducing board space. Consider the 1.7V to 5.5V supply range compatibility with your logic levels. The extended temperature range supports harsh industrial environments.

Part Context

This part belongs to the ADuM140 series of quad-channel digital isolators from Analog Devices. The series leverages CMOS process technology combined with iCoupler isolation. Variants within the family differ by channel directionality and package type, such as the SOIC or SSOP options, while maintaining similar core isolation specifications and data rate capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers include ADUM140D1BRZ. Verify that the alternative maintains the required 4:0 channel configuration and unidirectional operation. Check for any differences in package dimensions or pinout assignments before integration.
