ADUM131E1BRWZ-RL

Overview

The ADUM131E1BRWZ-RL is a triple-channel digital isolator from Analog Devices, utilizing iCoupler technology with integrated microtransformers. It features a 150 Mb/s data rate and supports unidirectional signal transmission across three channels. The device operates on a supply voltage range of 1.8 V to 5 V, with a typical operating current of 8.8 mA. It provides an isolation voltage of 3000 Vrms and exhibits a propagation delay of 7.2 ns. The component is housed in a 16-pin SOIC-W package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates microtransformers for magnetic coupling-based signal isolation
• Provides robust high-speed data transmission at 150 Mb/s
• Supports wide supply voltage operation from 1.8 V to 5 V

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics interfaces for noise immunity

Procurement Notes

Verify the specific suffix 'E1' against official Analog Devices documentation to confirm channel configuration and insulation ratings. Ensure the SOIC-W package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement specifications.

Selection Notes

Select this component when high-speed data rates up to 150 Mb/s are required alongside robust isolation capabilities. The wide operating temperature range makes it suitable for demanding industrial environments. Consider the low power consumption relative to its speed when designing battery-operated or thermally constrained systems.

Part Context

This part belongs to the ADuM131E series of triple-channel digital isolators. It leverages Analog Devices' proprietary iCoupler technology to replace traditional optocouplers in many applications. The series is designed for general-purpose isolation needs where high reliability and small form factor are critical.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM131 family, such as the ADUM1311 series, noting differences in data rate and insulation voltage. Verify that any substitute maintains the required 150 Mb/s performance and 3000 Vrms isolation rating.
