Hi, I'm currently working on making a level shifting circuit that is supposed to take an input voltage (somewhere from the 0-5V range or 2.5-4.5V range) and shift it between 0-2.5V as the input for an xmega chip. We are currently trying to use a differential op amp circuit with the op amp AD8036 and are using this as a reference for building the circuit:
we were having trouble building the correct gain for this circuit though, since the calculations we did by hand got us negative resistances, so if anyone has any tips as to how to select the correct resistances, or if another circuit would be better, the help would be awesome.
Thanks
