"Uncertainty" refers to the uncertainty of the temperature measurement when performing the 2-point calibration trim
as described in the application note. These graphs assume 11-bit temperature conversion. The accuracy can be
improved further through software correction. See the application note referenced as "Note 18" on the previous
page for details.
