SPI Isolators

Analog Devices has your isolated SPI bus covered with our dedicated serial peripheral interface (SPI) digital isolators. SPIsolators® are built with our proven iCoupler® technology and offer a small footprint, simple design-in, fast speeds, and high data integrity. Unlike optocouplers, ADI’s SPI isolator solutions increase performance and reduce board space, providing a simple, compact solution for isolated SPI data communications.
