power rail to ground. It allows a single supply to be used instead of a dual supply.
JMP2
This jumper allows the REFA pin on the INA149 to be connected to ground or the external reference op amp. The shunt on the jumper
can be removed as well to allow an external reference to be attached to the REFA test point.
