ADUM230E0BRIZ

Overview

The ADUM230E0BRIZ is a robust digital isolator from Analog Devices, featuring three unidirectional channels in a 16-lead SOIC package. It utilizes magnetic coupling technology to provide 5000 Vrms isolation voltage with a data rate of 150 Mb/s and a propagation delay of 7.2 ns. The device operates on a supply voltage range of 1.7 V to 5.5 V, drawing 9.4 mA of working power current. It supports a common-mode transient immunity of 75 kV/µs and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission across isolation barriers
• Provides high common-mode transient immunity to prevent false triggering in noisy environments
• Supports level translation between 1.8 V and 5 V domains for versatile interface compatibility

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high voltage differentials

Procurement Notes

Verify the specific suffix 'E0' to confirm the 3:0 channel configuration and unidirectional polarity. Ensure the SOIC-16 package width matches your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Confirm availability as supply may be restricted in certain regions.

Selection Notes

Select this component when three isolated bidirectional or unidirectional paths are required in a compact surface-mount form factor. Consider the 7.2 ns propagation delay for timing-sensitive applications. Evaluate the 9.4 mA power consumption against system energy budgets. Ensure the 5000 Vrms isolation rating exceeds the maximum circuit potential difference.

Part Context

This part belongs to the ADUM230E series of robust digital isolators. It shares the same core magnetic coupling architecture as other members but differs in channel count and directionality. The series is designed for general-purpose isolation where high reliability and low dynamic power consumption are critical design parameters.

Replacement Considerations

The ADUM230E1BRIZ offers a similar 3-channel configuration but may differ in input/output orientation or specific electrical characteristics. Verify pin-to-pin compatibility and functional equivalence before substitution. Consult official datasheets for detailed parameter comparisons.
