CM input range of instrumentation amp

  1. Jan 25, 2009 #1
    Can anyone tell me how to calculate the common-mode input range of an instrumentation amplifier with all op-amps biased from +15V to -15V assuming all op-amps can swing rail to rail.

    you should look at the specs on the datasheet for your amp

    Looks like homework. And we'd need a schematic.
