Digital Isolators are electronic components designed to achieve electrical isolation between circuits. It uses isolation techniques such as capacitive coupling, magnetic coupling, or optoelectronic coupling to cut off direct electrical connections between circuits without affecting signal transmission, thereby improving the safety and stability of the system. A digital isolator typically consists of one or more light-emitting diodes (LEDs), optocouplers, voltage adjustment circuits, operational amplifiers, etc. The design principle is based on non-contact transmission of signals to ensure accurate transmission of signals between different circuits without generating electrical connections. The optocoupler consists of a light-emitting diode and a photosensitive diode. The input signal is converted into a light signal through the light-emitting diode, and then the light signal is converted into an output signal through the photosensitive diode, achieving the purpose of electrical isolation
