ADUM250N1BRIZ

Overview

The ADUM250N1BRIZ is a robust five-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It provides unidirectional signal isolation with a voltage rating of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mbps with a typical propagation delay of 7.2 ns. Operating on supply voltages between 1.7 V and 5.5 V, it features three forward channels and two reverse channels. The component operates within a temperature range of -40°C to +125°C and dissipates up to 2.78 W.

Feature Summary

• Provides galvanic isolation for high-speed digital signals using magnetic coupling technology
• Ensures signal integrity through high common-mode transient immunity capabilities
• Supports flexible channel configurations with independent input and output sides

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reliable patient isolation barriers
• Power electronics control circuits demanding high-voltage separation

Procurement Notes

Verify the specific suffix N1 against official Analog Devices documentation to confirm the exact channel configuration and pinout. Ensure compatibility with system voltage levels and thermal requirements before integration. Confirm RoHS compliance status via the manufacturer's current datasheet. Check for any recent lifecycle notices or recommended replacements directly from the supplier.

Selection Notes

Select this component when unidirectional isolation is required for multiple digital lines. Consider the 150 Mbps data rate and 7.2 ns delay for timing-sensitive applications. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power dissipation characteristics with alternative isolators if thermal management is constrained.

Part Context

This part belongs to the ADuM family of digital isolators, which utilize iCoupler technology for signal transmission. The series offers various channel counts and isolation ratings. The ADUM250 variant specifically targets general-purpose isolation needs with balanced performance metrics for speed and reliability in harsh environments.

Replacement Considerations

Consult Analog Devices documentation for direct cross-references. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
