ADUM231E1BRWZ

Overview

The ADUM231E1BRWZ is a robust digital isolator featuring three independent channels with a 2:1 channel configuration. It utilizes magnetic coupling technology to provide high-speed data transmission at rates up to 150 Mbps. The device supports unidirectional signal transfer and offers level translation capabilities between supply voltages ranging from 1.8 V to 5 V on both sides. It ensures electrical isolation with a rated insulation voltage of 5000 Vrms and exhibits a common-mode transient immunity of 75 kV/µs. Operating within an extended temperature range of -40°C to +125°C, it delivers low dynamic power consumption and includes fail-safe options for reliable operation in harsh industrial environments.

Feature Summary

• Robust magnetic coupling isolation technology providing high reliability
• Supports bidirectional level translation across 1.8 V to 5 V domains
• High common-mode transient immunity for noise-resistant performance
• Extended operating temperature range suitable for industrial applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage isolation barriers
• Power metering circuits for energy monitoring
• Inverter drives and motor control interfaces

Procurement Notes

Verify the specific suffix (BRWZ) to confirm the SOIC-16 package and reel/cut-tape availability. Confirm RoHS compliance status as per current manufacturer documentation. Check for any product change notifications that may affect pinout or specifications. Ensure the 2:1 channel configuration matches your circuit design requirements before ordering.

Selection Notes

Select this component when a 2:1 channel ratio is required for asymmetric data paths. The 150 Mbps data rate suits moderate-speed serial communication protocols. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate power consumption against system thermal constraints, noting the low dynamic power characteristic.

Part Context

This part belongs to the ADUM231E family of digital isolators from Analog Devices. The series is characterized by its use of iCoupler technology for compact, high-performance isolation. Variants within the family differ primarily in channel count, directionality, and packaging options while maintaining similar core electrical characteristics.

Replacement Considerations

Direct substitutes include other ADUM231E variants such as ADUM231E0BRWZ, which shares the same package and core specifications but may differ in channel directionality or internal configuration. Verify functional equivalence regarding the 2:1 channel layout and isolation ratings before substitution.
