    Dear everybody
    In the attached circuit I need to replace the auto offset switch in the second channel (between AD524 output and TL082) and also the gain select switch by FET switches

    I need help in choosing a FET model that can be controlled using 0 or 5 or -5 volts

    thank you

    Hello,

    Did you think of the 4066 as a switch?

    Greetings,
