ADUM230E1BRIZ-RL

Overview

The ADUM230E1BRIZ-RL is a robust digital isolator from Analog Devices, featuring three unidirectional channels in a 16-SOIC package. It utilizes magnetic coupling technology to provide an isolation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device exhibits a common-mode transient immunity of 75 kV/µs and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a propagation delay of 7.2 ns and a supply current of 9.4 mA.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission across isolation barriers without optical components.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Offers general-purpose digital isolation with configurable channel directions for versatile interface applications.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment interfaces needing reliable signal separation for patient safety compliance.
• Power electronics monitoring circuits where high-voltage noise rejection is critical.

Procurement Notes

Verify the specific suffix E1 against official Analog Devices documentation to confirm pinout and functional compatibility. Confirm availability status as distribution channels may indicate limited stock or restricted supply conditions. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required in a compact surface-mount package. Consider the 5000 Vrms isolation rating and 75 kV/µs CMTI for high-noise industrial environments. Evaluate the 150 Mb/s data rate capability against your system's communication speed requirements to ensure adequate performance margins.

Part Context

This part belongs to the ADUM230 series of triple-channel digital isolators. It is designed to replace traditional optocouplers by offering superior performance in speed, power consumption, and reliability. The series is characterized by its use of silicon dioxide insulation layers and copper coils for magnetic signal transfer.

Replacement Considerations

Check for direct substitutes within the ADUM230 family, such as ADUM230E1BRIZ, noting that packaging variations like reel versus tube do not alter functionality. Verify equivalent isolation ratings and channel counts when considering cross-brand alternatives.
