ADUM240E0BRWZ

Overview

The ADUM240E0BRWZ is a quad-channel digital isolator from Analog Devices utilizing iCoupler magnetic coupling technology. It provides four unidirectional signal channels with a maximum data rate of 150 Mb/s and a typical propagation delay of 7.2 ns. The device operates on a single power supply ranging from 1.7 V to 5.5 V, drawing approximately 11.8 mA of quiescent current. It features a 5000 Vrms isolation voltage rating and supports an operating temperature range from -40°C to +125°C. Housed in a 16-lead SOIC package, it offers high common-mode transient immunity for robust noise rejection.

Feature Summary

• Integrates four independent unidirectional signal paths within a single compact package.
• Employs iCoupler magnetic coupling technology to achieve high-speed digital isolation without optical components.
• Provides robust protection against radiated and conducted noise through high common-mode transient immunity.
• Supports wide supply voltage ranges and extended industrial temperature operations.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment interfaces needing certified electrical safety isolation.
• Power electronics monitoring circuits for inverters and motor drives.
• Data acquisition systems connecting isolated measurement domains to central processors.

Procurement Notes

Verify the specific suffix BRWZ to confirm the tape-and-reel packaging format and lead-free status. Confirm that the E0 designation aligns with the required regulatory certifications for your target market. Check current availability as this component may have restricted supply status. Ensure the 16-SOIC footprint matches your PCB layout constraints before finalizing orders.

Selection Notes

Select this model when four unidirectional channels are sufficient for the application design. Consider the ADUM240E series if higher common-mode transient immunity than older generations is required. Evaluate the 150 Mb/s data rate against system timing requirements. Compare the 16-SOIC package dimensions against space-constrained designs versus alternative pinout options.

Part Context

This component belongs to the ADuM240E family of robust quad-channel digital isolators. It represents an evolution in iCoupler technology, offering improved performance metrics over previous iterations like the ADUM2401. The family focuses on providing reliable isolation in noisy environments while maintaining low power consumption and small form factors suitable for modern electronic designs.

Replacement Considerations

The ADUM240E0BRIZ serves as a tube-packaged equivalent with identical electrical characteristics. Verify pin compatibility and thermal performance when substituting between reel and tube formats. No functional changes are indicated by the suffix variation alone.
