Overview
The ADuM3150ARSZ is a 6-channel SPIsolator™ digital isolator designed by Analog Devices, Inc., specifically optimized for isolated serial peripheral interfaces (SPIs). This device leverages Analog Devices' iCoupler® chip scale transformer technology to achieve low propagation delay and high-speed data transfer. It is particularly suited for applications requiring high-speed SPI communication with robust isolation between the master and slave sides.
