Hi Can any body help an aging brain? I want to compare two 0 to 10 vdc signals and output the resulting difference as 0 to 10 vdc. I have tried a couple of circuits using comparators but have come up with the problem of a limited output range. I thought it would be easy top achieve but I seem to be wasting a lot of time going round in circles. Any body have any ideas? Many thanks.
