ADUM242D1BRWZ

Overview

The ADUM242D1BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four independent channels with a 2:2 input-to-output configuration in a 16-pin SOIC package. The device supports data rates up to 150 Mbps and offers a minimum common-mode transient immunity of 75 kV/µs. It operates on supply voltages ranging from 1.7 V to 5.5 V with a typical quiescent current of 11 mA per side. Key electrical parameters include a maximum propagation delay of 13 ns, an isolation voltage rating of 5000 Vrms, and an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity to maintain data integrity in electrically noisy environments.
• Supports bidirectional communication with independent power domains on both sides of the isolation barrier.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment needing reliable signal isolation for patient safety compliance
• Power electronics interfaces for monitoring and control circuits

Procurement Notes

Verify the specific suffix (BRWZ) to confirm the tube packaging format, as reel variants exist. Confirm RoHS compliance status through official documentation before integration. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the 16-SOIC footprint matches your PCB design constraints. Validate that the 5000 Vrms isolation rating meets your system's safety requirements.

Selection Notes

Select this component when four isolated channels are required within a single package to save board space. Choose the BRWZ variant specifically if tube packaging is preferred over reel or cut tape options. Consider the 150 Mbps speed limit for applications not requiring higher throughput. Verify that the 1.7 V to 5.5 V supply range aligns with your system's logic levels. Evaluate the 13 ns propagation delay against your timing budget.

Part Context

This part belongs to the ADuM242D series of quad-channel digital isolators. It shares core specifications with the ADUM242E series but may differ in manufacturing lot or specific qualification standards. The D1 suffix typically denotes a specific pinout or functional configuration within the family. It is designed to replace older transformer-based isolation solutions in compact designs.

Replacement Considerations

The ADUM242D0BRWZ is a confirmed substitute within the same series offering identical electrical characteristics. The ADUM242E1BRWZ serves as another compatible alternative with potentially different qualification grades. Verify pin compatibility and thermal performance when swapping between these variants.
