ADUM250N1BRIZ-RL

Overview

The ADUM250N1BRIZ-RL is a robust five-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a 5/0 channel configuration with unidirectional data flow and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 1.7 V to 5.5 V and provides an insulation voltage of 5000 Vrms. Packaged in a 16-pin SOIC, it functions reliably between -40°C and +125°C.

Feature Summary

• Provides galvanic isolation via proprietary magnetic coupling architecture
• Supports high-speed digital communication at 150 Mb/s data rates
• Features robust 5000 Vrms insulation voltage capability
• Includes five independent unidirectional channels for versatile system integration

Applications

• Industrial automation control systems requiring isolated signal paths
• Medical equipment needing patient isolation barriers
• Power electronics monitoring circuits
• Data acquisition systems with ground potential differences

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm availability status as distribution may vary. Ensure compatibility with existing PCB footprints for the 16-SOIC package. Check for moisture sensitivity levels prior to soldering processes. Validate that the 5/0 channel count meets the design requirements.

Selection Notes

Select this component when five isolated unidirectional channels are required. Consider the 150 Mb/s speed limit for signal integrity. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power consumption characteristics with alternative isolators. Ensure the operating temperature range fits the environmental conditions.

Part Context

This part belongs to the ADUM250N series of digital isolators. It shares architectural similarities with other ADUM devices but offers a specific 5/0 channel layout. The series is known for low power consumption and high reliability in noisy environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADUM family. Verify if higher channel counts or different configurations are needed. Ensure replacement parts maintain the same isolation voltage and data rate specifications.
