ADUM231E1BRWZ-RL

Overview

The ADUM231E1BRWZ-RL is a robust digital isolator from the Analog Devices iCoupler family, featuring three independent channels with a 2:1 input-to-output configuration. It utilizes magnetic coupling technology to provide electrical isolation rated at 5000 Vrms. The device supports unidirectional data transmission at speeds up to 150 Mbps and exhibits a typical propagation delay of 7.2 ns. It operates on supply voltages ranging from 1.8 V to 5 V and maintains functionality within an industrial temperature range of -40°C to +125°C. Packaged in a 16-lead SOIC, it draws approximately 8.8 mA of operating current.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for high-speed signal isolation
• Provides robust common-mode transient immunity to minimize noise interference
• Supports flexible level translation across 1.8 V to 5 V logic domains
• Features fail-safe design options to ensure defined output states during fault conditions

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering circuits for energy monitoring
• Inverter drives and motor control applications

Procurement Notes

Verify the specific suffix (E1) against the official Analog Devices datasheet to confirm channel configuration and pinout compatibility. Ensure the SOIC-16 package dimensions match the target PCB footprint. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the end application. Check for RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a 2:1 channel ratio is sufficient for the interface design. Consider the 150 Mbps data rate limit for high-speed communication needs. Evaluate the 8.8 mA quiescent current against power budget constraints. Verify that the 16-lead SOIC package fits the available board space compared to smaller alternatives.

Part Context

This part belongs to the ADUM231E series of general-purpose digital isolators. It shares the core iCoupler architecture with other variants in the family but differs in channel count and configuration. The E1 suffix typically denotes the specific 2:1 channel arrangement within the broader product line.

Replacement Considerations

Cross-reference with ADUM231E0BRWZ-RL or ADUM231E1BRIZ-RL for alternative package or reel options. Verify functional equivalence before substitution.
