    Hi,

    I'm currently building two circuits that is needed to send an output of constant 5V where one of it supports an input of 0-5V wherelse another circuit supports any voltage above 5V. This two circuits is then combined into one. How do i isolate either of the circuit when the other circuit is running?

    eg : if circuit A is running producing a 5V output, circuit B must be isolated.

    Tried relays but it doesnt work due to the magnetization flux in the relay causing the switching to be inaccurate.

    Any other possibilities with any analog components?

    Your description makes no sense. :( Maybe you could add a block diagram of what you have in mind. And...maybe describe the big picture...what you are trying to accomplish in the real world.
