Digital isolators configured for SPI communications links
Analog Devices has added a family of digital isolator devices optimised for serial peripheral interface (SPI) communications systems. The ADuM315x SPIsolator digital isolator family handles up to 40-MHz SPI clock speeds, making these digital isolators over six times faster, over 80% smaller and as much as 85% less expensive than competing optocoupler- or digital isolator-based solutions. Faster SPI clock speeds enable higher throughout in data acquisition systems, allowing for higher performance and more rapid system response times. A high level of functional integration provides system designers with a simple solution for isolating high-speed SPI signals along with commonly required low-speed status and control signals in a single package.
The ADuM315x family supports a range of high-data-rate, SPI communications applications including distributed control systems, programmable logic controllers, and sensor monitors used in industrial automation, instrumentation equipment and motor controls.
