I am using the ina125 chips to make a load cell with six channels and the bridges have different bridge voltages gain etc, the ina125 chip is good as it integrates everything. I have a few questions.
1-what is the VrefBG pin 13 for it does seem to be to supply a reference voltage to an external circuit - I have not understood the datasheet explanations - can a set the bridge voltage to what I want?

2-IIs it possible to connect the to use a potentiometer to change the input into the IAref pin 5 to set the initial bridge voltage with the required offset
