(1) The typical value includes one sigma statistical variation.
(2) Integral nonlinearity is defined as the maximum deviation from a straight line passing through the end-points of the ideal ADC transfer
function expressed as number of LSBs or as a percent of the specified linear full-scale range FSR.
(3) Offset error drift is calculated using the box method, as described by the following equation:
TCEO = (valueMAX - valueMIN) / TempRange
(4) Gain error drift is calculated using the box method, as described by the following equation:
TCEG (ppm) = ((valueMAX - valueMIN) / (value x TempRange)) X 106
