Requirements for selection of linear optocouplers

　　1. Operating frequency range: Select the appropriate operating frequency range according to the requirements of the application scenario. Different operating frequency ranges have different requirements for the response speed, bandwidth, and other performance of optocouplers.

　　2. Optocoupler output current: Select the appropriate optocoupler output current based on the current requirements of the controlled component. Generally speaking, the larger the output current, the stronger the driving capability of the optocoupler.

　　3. Isolation voltage: Select an appropriate isolation voltage based on the isolation requirements of the system. The higher the isolation voltage, the better the isolation performance of the system, but the cost will also increase accordingly.

　　4. Temperature characteristics: Consider the temperature range of the working environment and select a linear optocoupler with appropriate temperature characteristics. Optocouplers with good temperature characteristics can maintain stable performance at different temperatures.
