A technical performance-based view of opto-isolators and digital isolators | EDN

https://www.edn.com/design/analog/4461000/A-technical-performance-based-view-of-opto-isolators-and-digital-isolators Galvanic isolators are devices that couple an electrical data or control signal across an insulation barrier without any flow of current through it, thereby enabling signals to be transferred while blocking noise. The insulation barrier also safeguards equipment and human operators from high voltages. The earliest isolators were optically coupled devices, also called opto-isolators
