I am using a pair of strain gauges to make a weight scale. The strain gauges are the three-wire type that you can by on Amazon or Sparkfun. The strain gauges form a full wheatstone bridge, whose differential output voltage varies from -6mV to around 10mV. I'd like to amplify this signal and then sample with an ADC. But my board does not have a negative voltage supply.
How can I shift the differential voltage so that it starts out non-negative, and remains positive for the rest of its swing. In other words, make the differential output from the wheatstone bridge go from 0mV to 16mV?
For reference, this is the circuit I am using, from the INA332 datasheet.
