ADUM251N1BRIZ-RL

Overview

The ADUM251N1BRIZ-RL is a robust five-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features four unidirectional forward channels and one reverse channel within a 16-lead SOIC package with increased creepage distance. The device operates on a single power supply ranging from 1.7 V to 5.5 V, drawing a typical operating current of 15 mA. It supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns and an isolation voltage of 5000 Vrms. The component functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Provides robust 5 kVrms insulation using magnetic coupling technology for high noise immunity.
• Integrates four forward and one reverse channel in a compact 16-lead SOIC package.
• Includes fail-safe circuitry to ensure defined output states during input loss or power-down events.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment needing reliable signal separation for patient safety compliance.
• Power electronics interfaces for monitoring and control circuits in high-voltage environments.

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Ensure the selected variant matches the required channel configuration and package type for your design integration needs.

Selection Notes

Choose this component when a five-channel isolator with mixed directionality is required. The 16-lead SOIC footprint offers increased creepage distance compared to standard packages. Consider the 150 Mb/s data rate limit and 5.5 V maximum supply voltage when designing the interface circuitry.

Part Context
