ADUM231D0BRWZ

Overview

The ADUM231D0BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a data rate of 150Mbps and 75kV/µs common-mode transient immunity. The device features input disable functionality for 2:1 channel directionality, operates on 3V to 5.5V supplies, and is housed in a 16-SOIC package.

Feature Summary

• Triple-channel isolation with configurable 2:1 directionality via input disable pins
• High-speed data transmission at 150Mbps with low propagation delay
• Robust noise immunity characterized by 75kV/µs common-mode transient rejection
• Integrated magnetic coupling eliminates need for external transformers

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces demanding high safety isolation
• Power electronics gate drive circuits for inverters and converters
• Test and measurement instrumentation isolated communication links

Procurement Notes

Verify the specific suffix 'BRWZ' matches the required tape-and-reel packaging configuration. Confirm that the 5000Vrms isolation rating aligns with your system's safety standards. Ensure the 16-SOIC footprint corresponds to your PCB layout constraints before finalizing orders.

Selection Notes

Select this component when three isolated channels are needed with asymmetric data flow capabilities. The input disable feature allows dynamic channel management, making it suitable for multiplexed applications. Compare against single-channel alternatives if fewer isolation points are sufficient for the design.

Part Context

This part belongs to the ADuM231D series of robust digital isolators. It represents Analog Devices' iCoupler technology, which integrates transformer windings on-chip. The series is designed for applications requiring high reliability and small form factors compared to traditional optocouplers.

Replacement Considerations

Direct substitutes include ADUM231D1BRWZ-RL for different directionality configurations. Cross-reference with ADUM231D2BRWZ-RL for alternative pinout options. Verify compatibility with existing driver ICs when replacing legacy optocoupler designs.
