Overview
The ADuM4150ARIZ, produced by Analog Devices Inc., is a 6-channel SPIsolator™ digital isolator optimized for isolated serial peripheral interfaces (SPIs). This component leverages Analog Devices' iCoupler® chip scale transformer technology to provide high-speed signal isolation. It is designed to support SPI clock rates of up to 40 MHz in delay clock mode and up to 17 MHz in 4-wire mode, making it suitable for applications requiring high-speed data transfer and isolation.
