ADUM250N0BRIZ-RL

Overview

The ADUM250N0BRIZ-RL is a robust digital isolator manufactured by Analog Devices Inc., housed in a 16-pin SOIC package. It provides five independent channels of isolation with a unidirectional data flow configuration. The device supports data rates up to 150 Mbps and offers high common-mode transient immunity of 100 kV/µs. It operates within a supply voltage range of 2.7 V to 5.5 V for both sides and functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Features high common-mode transient immunity to reject noise spikes
• Supports unidirectional signal transmission across five isolated channels

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing patient isolation barriers
• Power electronics control interfaces

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the exact channel count and directionality match your schematic requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range aligns with your environmental specifications. Validate pinout compatibility with your PCB layout before finalizing procurement.

Selection Notes

Select this component when five isolated channels are required for unidirectional communication. Consider the 150 Mbps data rate limit for signal speed requirements. Evaluate the 100 kV/µs CMTI rating against the noise environment of your application. Compare power consumption metrics if energy efficiency is a critical design constraint.

Part Context

This part belongs to the ADuM family of digital isolators from Analog Devices. These devices replace traditional optocouplers, offering superior performance in terms of speed, size, and reliability. The series is designed for applications demanding high isolation voltages and low power consumption.

Replacement Considerations

Check for direct cross-reference models within the ADuM series that offer similar channel counts and isolation ratings. Verify pin-to-pin compatibility if substituting with other SOIC-16 isolators. Ensure the replacement maintains the required 100 kV/µs CMTI specification.
