ADUM3152ARSZ-RL7

Overview

The ADUM3152ARSZ-RL7 is a seven-channel digital isolator from the ADuM315x SPIsolator series, designed for serial peripheral interface (SPI) communication systems. It features four high-speed channels supporting up to 17 MHz SPI clock speeds and three low-speed data channels operating at 250 kbps. The device utilizes magnetic coupling technology with a 3750 Vrms isolation rating and 25 kV/µs common-mode transient immunity. Powered by a 3 V to 5.5 V supply, it operates within a temperature range of -40°C to +125°C in a 20-lead SSOP package.

Feature Summary

• Optimized for SPI interfaces with dedicated low propagation delay and jitter on clock and data lines
• Integrates four high-speed and three low-speed channels in a single compact package
• Provides robust signal isolation via proprietary iCoupler magnetic coupling technology

Applications

• Distributed control systems in industrial automation
• Sensor monitoring in motor control applications
• Programmable logic controllers
• Instrumentation equipment requiring isolated SPI communication

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required reel quantity and packaging specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly. Cross-reference datasheet revisions to confirm parameter consistency against current design specifications.

Selection Notes

Select this component when designing isolated SPI links requiring mixed speed channels. The four high-speed paths support fast clock rates while three auxiliary channels handle status signals. Verify that the 3750 Vrms isolation barrier meets system safety standards. Ensure the 20-lead SSOP footprint fits the target PCB layout constraints.

Part Context

This part belongs to the ADuM315x family, which replaces discrete optocoupler solutions. The series offers significantly reduced size and cost compared to traditional isolation methods. It supports high-performance analog-to-digital converter sampling rates and simplifies system design by integrating multiple isolation functions into one package.

Replacement Considerations

The ADUM3151ARSZ-RL7 serves as a parameter-equivalent alternative within the same series. Both devices share identical channel counts and package types but may differ in specific timing characteristics or factory packaging configurations.
