Norwood, MA (06/24/2014) - Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance signal processing technology, today introduced a new family of digital isolator devices optimized for serial peripheral interface (SPI) communications systems. The ADuM315x SPIsolator™ digital isolator family is based on ADI’s award-winning iCoupler® digital isolator technology, which has been shipped in volumes exceeding one billion channels.
Supporting up to 40-MHz SPI clock speeds, the new digital isolators are over six times faster, over 80 percent smaller and cost as much as 85 percent less 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.

The highly integrated ADuM315x SPI digital isolator family simplifies the design of a complete SPI digital isolation solution by using just three components, compared to the 18 to 32 components required by alternative digital isolator- or optocoupler-based solutions. The ADuM315x family features low propagation delay and jitter in the CLK, MO-SI, MI-SO and SS channels to support SPI clock rates of up to 40 MHz. The new digital isolators also support the maximum sample rate for select ADI 12-, 16- and 18-bit precision A/D converters. The family has a 3.75 kVrms isolation rating and will be followed later in 2014 by SPIsolator devices rated to 5 kVrms.
