Optocouplers, Part 1: Principles and usefulness
The optocoupler — also called an optoisolator — is among the most useful, versatile, problem-solving components available to the design engineer. This small non-monolithic device does one thing and does it well, with minimal complications in most cases and no software. This FAQ will look at the operation principles, key parameters, and applications of this […]
