ADUM252N0BRIZ-RL

Overview

The ADUM252N0BRIZ-RL is a robust digital isolator from Analog Devices, featuring five channels in a unidirectional 3/2 configuration. It utilizes magnetic coupling technology to provide an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns and common-mode transient immunity of 100 kV/µs. Operating on a supply voltage range of 1.7 V to 5.5 V, it draws a typical operating current of 13.7 mA. Packaged in a 16-pin SOIC W tube, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation via magnetic coupling technology for reliable signal transmission across potential barriers.
• Features high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports high-speed data communication with low propagation delay suitable for demanding digital interfaces.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient safety isolation
• Power electronics control circuits

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package orientation and tape/reel specifications match design requirements. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions account for moisture sensitivity classification prior to assembly.

Selection Notes

Select this component when unidirectional isolation is required for multiple signal lines simultaneously. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate power consumption against system thermal limits given the 13.7 mA typical current draw. Verify that the 5000 Vrms isolation rating meets safety standards for the specific application voltage levels.

Part Context

This part belongs to the ADuM252N series of digital isolators, designed for general-purpose isolation applications. It complements other variants in the family by offering a specific channel count and polarity configuration. The series emphasizes reliability and speed for modern industrial and commercial electronic designs.

Replacement Considerations

Cross-reference with ADUM252N1BRIZ-RL for similar specifications but different channel configurations. Ensure pin compatibility and isolation ratings match before substituting. Verify that any alternative maintains the same magnetic coupling technology and performance metrics.
