ADUM230E0BRIZ-RL

Overview

The ADUM230E0BRIZ-RL is a robust digital isolator from Analog Devices, featuring three unidirectional channels with an ISO 3:0 configuration. It utilizes magnetic coupling technology to provide electrical isolation rated at 5000 Vrms. The device supports data rates up to 150 Mb/s and exhibits a maximum propagation delay of 7.2 ns. Operating within a supply voltage range of 1.7 V to 5.5 V, it draws a typical operating supply current of 9.4 mA per channel. The component 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 via proprietary magnetic coupling technology for signal integrity
• Features three independent unidirectional channels for general-purpose digital isolation
• Includes high common-mode transient immunity characteristics for noise rejection

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced safety isolation barriers
• Power electronics control circuits for gate drive feedback

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the E0 variant designation matches the required 3-channel unidirectional specification. Ensure the SOIC-16 footprint aligns with the target PCB layout. Check for any recent product change notifications regarding manufacturing updates. Validate that the 5000 Vrms isolation rating meets the safety standards of the end application.

Selection Notes

Select this component when three isolated digital signals are required in a single package. The unidirectional nature suits applications where data flows strictly from source to destination. Consider the 150 Mb/s speed limit against system timing requirements. Evaluate the 9.4 mA current consumption against power budget constraints. The wide operating temperature range supports harsh industrial environments.

Part Context

This part belongs to the ADUM230 series of digital isolators designed for robust performance. It complements other variants like the ADUM230D0BRIZ-RL which shares similar electrical characteristics but may differ in packaging or qualification status. The series emphasizes reliability and low power consumption for modern interface applications.

Replacement Considerations

The ADUM230D0BRIZ-RL is a functional equivalent within the same family. Verify pinout compatibility and isolation ratings before substitution. Ensure the replacement part meets the specific thermal and electrical requirements of the design.
