ADUM230E1BRWZ

Overview

The ADUM230E1BRWZ is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation with a data rate of 150 Mbps and 75 kV/µs common-mode transient immunity. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V, consuming 9.4 mA typical supply current per channel. It features unidirectional signal transmission in a 16-pin SOIC package, supporting an operating temperature range of -40°C to +125°C.

Feature Summary

• Robust magnetic coupling isolation technology for high reliability
• High common-mode transient immunity of 75 kV/µs
• Unidirectional signal transmission capability
• Wide operating voltage and temperature ranges

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing patient isolation barriers
• Power management circuits with isolated feedback loops
• Instrumentation interfaces demanding high noise immunity

Procurement Notes

Verify the specific suffix (WZ vs BRIZ) against the datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current availability as distribution may vary by region. Ensure the selected variant matches your board space constraints for the 16-SOIC package.

Selection Notes

Select this component when three independent unidirectional channels are required within a single package. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 150 Mbps data rate against system timing requirements. Compare power consumption at 9.4 mA per channel against battery-operated constraints. Verify compatibility with logic levels supported by the 1.7 V to 5.5 V supply range.

Part Context

This part belongs to the ADUM230 series of robust iCoupler digital isolators from Analog Devices. It shares architectural similarities with other members like the ADUM230E1BRIZ but differs in packaging and reel configuration. The series emphasizes high reliability and low skew for industrial and medical environments.

Replacement Considerations

The ADUM230E1BRIZ is a pin-compatible alternative differing primarily in tube packaging versus tape-and-reel. Verify that the change in packaging does not impact automated assembly processes. Both variants share identical electrical characteristics and functionality.
