Symmetric input

  1. Mar 14, 2010 #1
    I would like to ask you what it is meant by "symmetric input" in the instrumentational amplifier schematics and in the differential amplifier? I can`t understand what is the difference between symmetric and non symmetric input and output as parameters. Can anyone explain ?

    Probably they mean a balanced diferential input, like

    Vplus = A·sin(ωt), and

    Vminus = -A·sin(ωt)
