App note: Replacing traditional optocouplers with Si87xx digital isolators

Digital isolator from Silicon Labs app note shows pin compatible plus high performance replacment of incumbent optoisolators, link here (PDF) Opto-couplers are a decades-old technology widely used for signal isolation, typically providing safety isolation, signal level shifting, and ground loop mitigation. They are commonly used in a wide range of end applications, including data communication […]

App note: Understanding the safety certification of digital isolators

This application note summarizes the international safety standards and certifications that apply to digital isolators. Link here Digital isolators provide signal isolation and the level shifting required for the correct operation of many circuits. Equally important, they insulate the user from electric shock. With basic human safety considerations so pertinent here, these isolators must undergo […]
