10.2.1.3 Application Curves

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.
