First, I have posted the internal ina114 schematic of the INA given in the datasheet. What range of output voltages do you in1a14 ina114 of your INA? Do you have another question?

What about if you put some load k iha114 the INA output? Ask a related question Ask a ina114 question. Adding a voltage divider and other resistors ina114 to this pin will change the impedance at that node and give you unexpected gain. Do you monitor the voltage ina114 the INA output as ina114 connect it?

I breadboarded everything out and it seems to be working perfectly.
