Can digital signals pass through isolation chips? The answer is yes. Digital signals can be transmitted through isolation chips. Isolation chips are mainly used to isolate signals for the purpose of electrical isolation, ground isolation, or optical isolation. Isolation chips typically consist of two parts: isolation front-end and isolation back-end.
The isolation front-end is responsible for isolating the input signal, usually using magnetic or optical isolation methods. In digital circuits, optical isolation is a common method, and the isolation front-end uses devices such as light-emitting diodes (LEDs) and photodiodes to convert input signals into optical signals to avoid electrical interference.
The isolation backend is responsible for receiving signals transmitted by the isolation frontend and converting them back to digital signal output. The isolation backend usually uses digital isolation to digitize, demodulate, and process the signals transmitted by the isolation frontend, and finally output digital signals.
Therefore, digital signals can be transmitted through isolation chips. In some application scenarios, such as industrial automation, power and electrical fields, isolation chips can help achieve signal isolation, prevent interference, and improve system security.
