ADUM131E0BRWZ

Overview

The ADUM131E0BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler technology to provide robust signal isolation. It features a 3750 Vrms isolation voltage and supports data rates up to 150 Mbit/s with a typical propagation delay of 7.2 ns. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V, drawing approximately 8.8 mA of quiescent current. It includes two unidirectional channels in one direction and one in the reverse direction, housed in a 16-pin SOIC package.

Feature Summary

• Utilizes iCoupler technology combining high-speed CMOS and monolithic air-core transformer capabilities for superior reliability compared to optocouplers.
• Provides high common-mode transient immunity of 75 kV/µs to resist radiated and conducted noise.
• Offers low propagation delay and pulse width distortion for precise timing applications.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power metering and energy management circuits

Procurement Notes

Verify the specific suffix (0BRWZ) against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Check for RoHS compliance status and moisture sensitivity levels before integration. Confirm availability as distribution status may vary by region.

Selection Notes

Select this component when three isolated channels are required within a compact surface-mount footprint. Ensure the operating voltage range of 1.8 V to 5.5 V aligns with your system logic levels. Consider the 150 Mbit/s data rate capability if higher throughput than standard isolators is needed.

Part Context

This part belongs to the ADuM131x series of triple-channel digital isolators. It serves as a modern replacement for traditional optocouplers, offering smaller size, lower power consumption, and better performance consistency across temperature variations due to its silicon-based magnetic coupling architecture.

Replacement Considerations

Direct substitutes include other parts within the ADuM131x family, such as the ADUM131E0BRZ or ADUM1311 variants, depending on specific data rate and packaging needs. Verify channel configuration and isolation voltage ratings when cross-referencing.
