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 extensive testing and certification to ensure user safety. This article briefly summarizes the international safety standards and certifications that apply to digital isolators. An example exercise using the MAX1493x family shows how an IC designer must use a data sheet and the standard’s specification tables to determine which digital isolator will be optimal for an application.
