ADUM231E0BRWZ-RL

Overview

The ADUM231E0BRWZ-RL is a robust triple-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a 5000 Vrms insulation voltage and supports data rates up to 150 Mbps. The device offers high common-mode transient immunity of 75 kV/µs and low propagation delay, with a maximum of 13 ns at 5 V operation. It operates within a supply voltage range of 2.25 V to 5.5 V and consumes approximately 8.8 mA of quiescent current per channel. Packaged in a 16-pin SOIC (0.295 inch width) format, it ensures reliable isolation in noisy environments.

Feature Summary

• Provides galvanic isolation between circuits using magnetic coupling technology
• Delivers high robustness against radiated and conducted noise interference
• Ensures signal integrity through high common-mode transient immunity
• Supports unidirectional data transmission across three independent channels

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high voltage differentials
• Test and measurement instrumentation for signal isolation

Procurement Notes

Verify the specific suffix 'E0' and package type 'BRWZ' against your schematic requirements. Confirm that the 5000 Vrms rating meets your safety standards. Check for RoHS compliance documentation. Ensure the SOIC-16 footprint matches your PCB layout. Validate operating temperature ranges for your specific environment.

Selection Notes

Choose this component when triple-channel isolation is required with high speed and robustness. Compare the 5000 Vrms rating against lower voltage alternatives if space is constrained. Consider the 150 Mbps data rate for bandwidth needs. Evaluate the 13 ns propagation delay for timing-sensitive applications. Assess power consumption relative to other isolators in the ADUM series.

Part Context

This part belongs to the ADUM231E family of general-purpose digital isolators. It shares the SOIC-16 package with variants like ADUM231D0BRWZ but differs in insulation voltage and channel configuration. The 'RL' suffix indicates reel packaging. It complements other ADUM devices offering single or quad-channel options for diverse isolation needs.

Replacement Considerations

The ADUM231D0BRWZ-RL is a related variant within the same family. Verify if the lower insulation voltage of the D-series suffices for your application. Both share similar pinouts and functionality but differ in specific electrical ratings.
