ADUM4154BRIZ-RL

Overview

The ADUM4154BRIZ-RL is a digital isolator from Analog Devices, designed for multiple slave isolation in SPI interfaces. It features seven channels with bidirectional data flow and magnetic coupling technology. The device supports data rates of 250 kb/s and 34 Mb/s, providing an insulation voltage of 5000 Vrms. Operating within a temperature range of -40°C to +125°C, it is housed in a 20-pin SOIC package.

Feature Summary

• Provides galvanic isolation for SPI bus systems using magnetic coupling technology.
• Supports bidirectional data transmission across seven independent channels.
• Engineered for high common-mode transient immunity in noisy environments.

Applications

• Multiple slave SPI interface isolation
• Industrial communication systems requiring galvanic separation
• Data acquisition systems with isolated sensor inputs

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the component matches the exact part number ADUM4154BRIZ-RL to guarantee compatibility with existing designs and regulatory requirements.

Selection Notes

Select this component when designing systems that require isolation for multi-slave SPI configurations. Consider the 7-channel count and bidirectional capability as primary selection criteria. Evaluate the 5000 Vrms insulation rating against system safety standards and operating voltage requirements to ensure adequate isolation margins.

Part Context

This part belongs to the ADUM4154 series of digital isolators manufactured by Analog Devices. It utilizes iCoupler technology for signal transmission. The BRIZ suffix denotes the industrial temperature grade and SOIC-W package variant. The -RL suffix specifies tape and reel packaging for automated assembly processes.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM4154 family. Verify if alternative packages like ADUM4154BRIZ offer identical electrical characteristics without the reel packaging requirement. Consult official substitution guides for any functional equivalents with updated specifications.
