ADUM240D1BRIZ-RL

Overview

The ADUM240D1BRIZ-RL is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four unidirectional channels with a data rate of 150 Mb/s and a maximum propagation delay of 7.2 ns. The device operates within a supply voltage range of 1.7 V to 5.5 V and features an isolation voltage of 5000 Vrms. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates four independent unidirectional signal paths for efficient multi-channel isolation
• Employs iCoupler magnetic coupling technology to eliminate the need for external transformer drivers
• Provides high common-mode transient immunity to protect against noise interference

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal transmission interfaces
• Power electronics gate drive circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel packaging configuration. Ensure compliance with RoHS directives and check for any recent product change notifications that may affect specifications or availability status.

Selection Notes

Select this component when four isolated bidirectional or unidirectional digital signals are required in a compact form factor. Consider the 150 Mb/s data rate limit and 5000 Vrms isolation rating against system requirements. Evaluate the SOIC-16 footprint constraints and thermal dissipation capabilities for the target application environment.

Part Context

This part belongs to the ADuM240 series of quad-channel digital isolators. It shares architectural similarities with other iCoupler devices but is distinct in its channel count and unidirectional configuration. It serves as a specialized interface solution for applications demanding high reliability and small physical size compared to traditional optocouplers.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout compatibility, isolation voltage ratings, and data speed specifications to guarantee functional equivalence without circuit redesign.
