ADUM3152BRSZ-RL7

Overview

The ADUM3152BRSZ-RL7 is a seven-channel digital isolator from the ADuM315x SPIsolator series, manufactured by Analog Devices Inc. It utilizes iCoupler magnetic coupling technology to provide signal isolation for Serial Peripheral Interface (SPI) communication systems. The device features four high-speed channels with low propagation delay and jitter, supporting up to 17 MHz SPI clock speeds, alongside three additional data channels operating at 250 kbps. It offers a 3750 Vrms isolation rating and operates within a supply voltage range of 3 V to 5.5 V. Packaged in a 20-lead SSOP, it integrates typically required control signals into a single component.

Feature Summary

• Integrates four high-speed SPI signal isolation channels with low propagation delay and jitter for reliable high-frequency communication
• Includes three additional data channels suitable for status and control signals within isolated systems
• Utilizes iCoupler magnetic coupling technology to eliminate the need for external transformer drive circuits

Applications

• Distributed control systems in industrial automation
• Sensor monitoring interfaces in programmable logic controllers
• Motor control applications requiring high-speed SPI isolation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BRSZ variant matches the required 20-lead SSOP package dimensions. Ensure compatibility with the target system's voltage levels and isolation requirements before procurement.

Selection Notes

Select this component when designing SPI interfaces requiring high data rates up to 17 MHz combined with lower speed control lines. It serves as a compact alternative to discrete solutions, reducing board space and component count compared to traditional optocoupler-based designs.

Part Context

This part belongs to the ADuM315x family, which includes variants like ADUM3150 and ADUM3151. These devices are optimized specifically for SPI bus isolation, offering higher performance than standard general-purpose digital isolators while maintaining a small footprint.

Replacement Considerations

Direct substitutes include other parts within the ADuM315x family, such as the ADUM3151 or ADUM3150, depending on the specific channel configuration and speed requirements needed for the application.
