A useful amp, a schematic would help.
This is a useful little differential instrument amp at a great price. Other sellers do have a schematic for it, but most of them are sold out. It is possible to use the AD620 datasheet to calculate a fixed gain resistor, which will be useful for many applications. Proto Supplies has a schematic for it.
