SPI (Serial peripheral interface) is one of the most widely used interfaces between microcontrollers and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others. Analog Devices has your isolated SPI bus covered with our dedicated SPI digital isolators which support this synchronous, full duplex master-slave-based interface. Options include devices built with ADI's proven iCoupler® technology and offering a small footprint, simple design-in, fast speeds, and high data integrity, as well as integrated µModules which require no external components. Our SPI isolator solutions increase performance and reduce board space. This simple, compact solution is ideal for isolated SPI data requiring communication across different ground potentials or through large common mode transients often found in Industrial PLCs (programmable logic controllers) and Instrumentation and data acquisition systems.
Safety and Regulatory Compliance Information
The iCoupler family of digital isolation products have been tested and approved by various regulatory agencies, including UL, CSA, VDE, TÜV, CQC, ATEX and IECEx. This table summarizes the achieved ratings for each product and includes links to copies of the actual safety certificates.
Whether as a component or as part of a larger system level solution, EMC compliance must be met, and the best EMC design practices occur at the start of the design. Be prepared for the certification process and get ahead of the game with our selection of resources.
