Hi Edgar Ripoll Vercellone, Thanks for providing the requested information It does seem like sensor is adding an error to your system, the plot where you are just measuring a resistor divider looks much cleaner (can you use the same units for all plots however? Some have a y-axis in volts, some in codes, it will be easier to compare if they are all the same. Codes should be fine) Can you explain your reference circuit to me? The schematic shows what looks like a true ratiometric reference on REFP0 and REFN0, where the bridge excitation voltage is directly used as the ADC reference voltage. I am not sure what the VREF- net is however, as this appears to be grounded. However, you have said that you are using a resistor divider for your reference, which I assume is the one shown in the bottom of the image below. It is not clear to me why would you use a resistor divider instead of the ratiometric reference, or why you have both. And are those matched resistors, or just two discrete components? -Bryan
