  • The role of optocouplers in high-frequency circuits

    The role of optocouplers in high-frequency circuits

    An optocoupler is a device that transmits electrical signals from one circuit to another, allowing communication between the two circuits via optical signals rather than a direct electrical connection. It uses light to do the job, which helps keep things safe. In this guide, you'll learn how they work and how you can use one in your own projects. Optocouplers are very useful when you need to isolate different sections of a circuit, for example in power. Optocouplers, also known as opto-isolators, uses infrared light to transfer electrical signals between two electrically isolated circuits and are commonly classified by their photosensitive output device What is an Optocoupler? An optocoupler (also called an opto-isolator, photo-coupler, or optical. There are many different applications for optocoupler circuits, so there are many different design requirements, but a basic design for an optocoupler providing isolation for example between two circuits, simply involves the choice of appropriate resistor values for the two resistors R1 and R2.
