Optocouplers are inherently limited by outdated LED-based technology, which exhibits significant output variation over input current, temperature and age. These variations reduce the operating performance and reliability over the optocoupler’s lifetime, resulting in increased design complexity and shorter life expectancy for end products. Because of their aging effects, optocouplers are often specified to last only 10 years, posing a serious problem for industrial system designers who want to develop products with 20+ year warranties. Read this white paper to learn how digital isolator evolution is driving the replacement of optocouplers, offering a higher performance and more reliable solution.
