ADUM142E0BRZ

Digital Isolators Overview

The ADUM142E0BRZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with two forward and two reverse directions. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. It provides an insulation voltage of 3750 Vrms and maintains a propagation delay of 15 ns. The component is housed in a 16-lead SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated digital channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust isolation performance with a rated insulation voltage of 3750 Vrms to protect sensitive circuitry.
• Supports unidirectional data flow with configurable channel orientation for flexible system design.
• Operates over an extended industrial temperature range to ensure reliability in harsh environments.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment interfaces needing high-voltage isolation for patient safety compliance
• Power electronics control circuits isolating gate drivers from logic controllers

Digital Isolators Procurement Notes

Verify the specific suffix 'BRZ' confirms the SOIC-16 package and lead-free RoHS compliance. Confirm the '0' designation indicates the 3750 Vrms insulation rating variant. Ensure the source document matches the manufacturer's official datasheet for the ADUM142E series to validate electrical parameters and pinout configurations before integration.

Digital Isolators Selection Notes

Select this component when a quad-channel solution is required for bidirectional or unidirectional isolation in compact designs. The SOIC-16 package offers a balance of isolation creepage distance and board space efficiency. Consider the 150 Mb/s data rate limit and 15 ns propagation delay against system timing requirements. Verify that the 3750 Vrms insulation rating meets the specific safety standards of the target application.

Digital Isolators Part Context

This part belongs to the ADUM142E family of robust quad digital isolators. It shares the core iCoupler architecture with variants offering different insulation ratings, such as the 3000 Vrms ADUM142E1BRZ. The family is designed for applications demanding high common-mode transient immunity and low power consumption compared to traditional optocouplers.

Digital Isolators Replacement Considerations

The ADUM142E1BRZ serves as a functional substitute but offers a lower 3000 Vrms insulation rating. Verify if the reduced isolation voltage meets the safety requirements of the specific application environment before swapping components.
