ADUM251N1BRIZ

Overview

The ADUM251N1BRIZ is a robust five-channel digital isolator from Analog Devices, housed in a 16-SOIC package. It provides 5000 Vrms isolation with a data rate of 150 Mb/s and operates on a supply voltage between 1.7 V and 5.5 V. The device features three forward channels and one reverse channel, delivering a typical propagation delay of 7.2 ns and rise/fall times of 2.5 ns. It supports an operating temperature range from -40°C to +125°C and includes high common-mode transient immunity.

Feature Summary

• Provides galvanic isolation for digital signals using magnetic coupling technology
• Supports unidirectional signal transmission across multiple independent channels
• Maintains signal integrity with low propagation delay and pulse width distortion

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix (N1) against official Analog Devices documentation to confirm channel configuration and pinout compatibility. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a five-channel isolator with unidirectional capability is required. Compare power consumption and channel count against alternatives like the ADUM252N series if bidirectional communication is needed. Verify that the 150 Mb/s data rate meets system timing constraints and that the 5000 Vrms rating satisfies safety isolation standards.

Part Context

This part belongs to the ADUM25xN family of robust digital isolators designed for high-reliability applications. It utilizes Analog Devices' iCoupler technology to provide compact, low-power isolation solutions. The N1 suffix typically denotes a specific channel configuration within the broader ADUM251 product line.

Replacement Considerations

Check for direct cross-reference part numbers such as ADUM251N1BRIZ-RL for reel packaging options. Verify functional equivalence with other five-channel isolators only after confirming identical pinouts and electrical characteristics.
