DIGITAL ISOLATOR
PRODUCT SELECTION
AND RESOURCE GUIDE
Spring 2015 Edition
Performance | Integration | Ef ficiency | Reliability | Safety
Digital isolators with iCoupler® technology enable designers to implement isolation in designs without the cost, size, power, performance, and
reliability constraints found with optocouplers. iCoupler digital isolators
also meet the wide range of creepage/clearance requirements and provide
up to 8 mm creepage. With more than 1.3 billion channels shipped into
the field, these magnetically isolated products meet the same rigid safety
standards as optocouplers.
We’ve Got Your SPI Bus Covered!
Utilizing ADI’s proven iCoupler technology, SPIsolator
digital isolators are dedicated SPI isolators that provide
a small footprint, ease of design, high speed channels,
and high data integrity. Unlike optocoupler and previous
digital isolator solutions, the SPIsolator offers the ability
to increase performance and lower cost all while reducing board space by utilizing a single compact form factor.
