ADUM242D1BRWZ-RL

Overview

The ADUM242D1BRWZ-RL is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage and supports data rates up to 150 Mbps with a common-mode transient immunity of 75 kV/µs. The device features four unidirectional channels arranged in a 2:2 configuration within a 16-pin SOIC package. Operating on a single supply voltage between 3 V and 5.5 V, it ensures reliable signal transmission across isolated boundaries with low propagation delay.

Feature Summary

• Provides high-reliability galvanic isolation using proprietary iCoupler magnetic coupling technology
• Supports high-speed data transmission with a maximum rate of 150 Mbps per channel
• Features robust noise immunity against fast-rising voltage transients at the isolation boundary
• Integrates four independent unidirectional logic channels in a compact surface-mount package

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced safety isolation for patient-connected circuits
• Power electronics monitoring and control applications with high-voltage switching
• Automotive electronic control units demanding reliable data isolation

Procurement Notes

Verify the specific suffix BRWZ-RL to confirm the reel packaging format and tape-and-reel quantity. Ensure the order matches the exact part number to avoid confusion with tube-packaged variants or different channel configurations within the same family. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this component when four unidirectional isolated channels are required for high-speed digital signals. The 5000 Vrms rating suits applications with significant potential differences between ground domains. Consider the 150 Mbps speed limit for bandwidth requirements and verify that the 16-SOIC footprint fits the design constraints compared to smaller alternatives.

Part Context

This part belongs to the ADuM242D series of digital isolators designed for general-purpose applications. It represents a solution for replacing traditional optocouplers in modern designs where higher speed and better reliability are needed. The series is widely used in industrial and automotive sectors for signal integrity enhancement.

Replacement Considerations

Direct substitutes include other parts within the ADuM242D family, such as the ADUM242D0BRWZ-RL, which shares similar electrical characteristics but may differ in internal channel mapping or pinout compatibility. Verify functional equivalence before swapping.
