    Hi,

    I want to reduce a circuit for sensing current (Hall Sensor used). In
    this circuit i measure current from two different motors on a single
    board. The current is sensed and fed to the Signal conditioning circuit
    which again combines both motor signals and generate fault signal. Is
    it possible to do so? Can i use a multiplexer to do the same? I have
    never used one..

    Thanks and regards.

    Hi, Nick

    I used a multiplexer for the same use like yours the other day. But I
    failed.
    Because the multiplexer has some on-resistance depending on the current
    following through it.
    May someone can help.
