using AD620 with load cell
Yes. What you need is a difference amplifier with gain. You can do this in a single stage, but I think you're better off doing it in two stages. First, create a voltage of 1.5 volts, and subtract that from your AD620 output. You can do that with a simple difference amplifier: one op amp and 4 equal resistors. You will now have a useable voltage swing of 0 to 2.2 volts. Then you make a non-inverting amplifier with a gain of a little more than 2, and boost your 0 to 2.2 to a 0 to 5 volt signal.
