ADUM4152BRIZ-RL

Overview

The ADUM4152BRIZ-RL is a seven-channel digital isolator from Analog Devices, designed specifically for isolated serial peripheral interface (SPI) applications. It features magnetic coupling technology with a 5000 Vrms insulation voltage and supports data rates up to 34 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and includes one auxiliary channel with configurable directionality. It exhibits a propagation delay of 16 ns and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Optimized for isolated SPI interfaces with dedicated channel configuration
• High common-mode transient immunity via magnetic coupling isolation
• Configurable auxiliary channel directionality for flexible system design

Applications

• Isolated SPI communication in industrial automation systems
• Data acquisition systems requiring galvanic isolation
• Medical equipment with strict safety isolation requirements

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity upon receipt as moisture sensitivity requires proper handling. Ensure ordering suffix matches required reel specifications. Cross-reference datasheet revisions to confirm parameter consistency before integration into production designs.

Selection Notes

Select this component when designing SPI-based isolated interfaces requiring seven signal paths. Evaluate power consumption against system thermal constraints given the 14 mA operating current. Consider the SOIC-20 package dimensions for PCB layout compatibility. Verify that the 5000 Vrms isolation rating meets specific safety standards for the target application environment.

Part Context

This part belongs to the ADuM4152 series of SPIsolator digital isolators. It integrates multiple isolated channels into a single compact package to reduce board space compared to discrete solutions. The series targets high-speed digital isolation needs where signal integrity and noise immunity are critical for reliable data transmission across isolation barriers.

Replacement Considerations

Check ADUM4152ARIZ for identical electrical characteristics without the reel packaging suffix. Verify pinout compatibility if substituting with other seven-channel isolators. Ensure replacement parts maintain the same 5000 Vrms isolation rating and SPI protocol support.
