ADUM242D0BRIZ

Overview

The ADUM242D0BRIZ is a robust quad digital isolator from Analog Devices, featuring four independent channels with a 2:2 channel configuration. It utilizes magnetic coupling technology to provide galvanic isolation between digital signals. The device supports data rates up to 150 Mb/s and offers an insulation voltage of 5000 Vrms. Operating within a supply voltage range of 1.7 V to 5.5 V, it exhibits a typical propagation delay of 7.2 ns and operates at a working power current of 11 mA. The component is housed in a 16-lead SOIC package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for digital signal transmission using magnetic coupling technology
• Features unidirectional signal flow across four independent channels
• Delivers high common-mode transient immunity for reliable operation in noisy environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage separation requirements

Procurement Notes

Verify the specific suffix BRIZ indicates the standard tube packaging format when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment. Cross-reference the datasheet revision date to ensure compatibility with existing design constraints.

Selection Notes

Select this component when a quad-channel unidirectional isolator is required for space-constrained designs. The SOIC-16 package offers a compact footprint suitable for dense PCB layouts. Consider the 150 Mb/s data rate limit when designing high-speed communication links. Evaluate the 5000 Vrms isolation rating against the system's safety standards and transient voltage expectations.

Part Context

This part belongs to the ADuM242D series of digital isolators from Analog Devices. The series focuses on providing robust isolation solutions for various industrial and commercial applications. The ADUM242D0BRIZ specifically addresses needs for four-channel isolation in a single package, simplifying board design compared to discrete solutions.

Replacement Considerations

Direct substitutes include other parts within the ADuM242 family, such as the ADUM242D1BRIZ or ADUM242D0BRWZ, depending on packaging preferences like reel versus tube. Verify pinout compatibility and electrical parameters before swapping components.
