3.8.2 Temperature Signal Compensation

Temperature is measured internally. Temperature correction contains both linear gain and offset terms as well as a second-order term to correct

for any nonlinearities. For temperature, second-order compensation for nonlinearity is always parabolic.

The correction formula is best represented as a two-step process as follows:
