Run leads out of both the positive and negative inputs and put a 1k-ohm resistor on each. Feedback one polarity around one resistor so that it bypasses the resistor and goes right to the input. Check out how a common-mode voltage amplifier works.<br><b>References : </b><br> You can use one power supply for both the plus and minus inputs.
