ADUM230E0BRWZ-RL

Overview

The ADUM230E0BRWZ-RL is a triple-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a robust isolation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 1.7 V to 5.5 V, with a typical quiescent current of 9.4 mA per channel. Propagation delay is specified at 7.2 ns, ensuring precise timing for high-speed applications. It is housed in a 16-pin SOIC package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using on-chip transformer technology
• Supports unidirectional signal transmission across three independent channels
• Offers high common-mode transient immunity for noise-sensitive environments

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance and lead times directly with the manufacturer or certified suppliers. Ensure storage conditions meet humidity sensitivity requirements prior to assembly. Cross-reference ordering part numbers carefully to match specific suffix designations for packaging variations.

Selection Notes

Select this component when triple-channel isolation is required with high voltage ratings. Consider the 150 Mb/s data rate limit for application compatibility. Evaluate power consumption constraints given the 9.4 mA operating current. Ensure the 16-SOIC package fits the PCB layout requirements. Verify thermal management capabilities for operation up to 125°C.

Part Context

This part belongs to the ADuM230E series of general-purpose digital isolators. It replaces older optocoupler technologies by offering smaller size and lower power consumption. The series is designed for robust performance in harsh industrial environments. Analog Devices integrates magnetic coupling technology to achieve reliable isolation without optical components.

Replacement Considerations

Direct substitutes include other ADuM230 variants with different packaging options such as ADUM230E0BRIZ. Check pinout compatibility before swapping packages. Verify that alternative parts maintain the same 5000 Vrms isolation rating and 150 Mb/s speed specifications.
