Performing a two-point calibration at 25°C removes the errors associated with offset voltage, gain error, and so forth. Figure 10-6 to Figure 10-8 show the measured error at different conditions. For a more detailed description on measurement procedure, calibration, and calculations, please refer to TIDU357.
