Note 9: The limits found in the following table supersede the limits shown in the Electrical Characteristics Table. The Accuracy specification includes errors due to
linearity, offset and gain. The accuracy specification includes effects of self heating with negligible digital output loading. Pull-up resistors should be maximized (10k
typical recommended), so that self heating due to digital output loading is negligible.
Limits at intermediate temperatures can be calculated using a straight line interpolation as shown in the following graphs:
Note 10: 12 bits + sign, two’s complement
Note 11: Linearity Error is defined as the worse case difference of an actual reading to that of a calculated reading derived from the straight line whose endpoints
are measured at 30˚C and 125˚C for the range of 30˚C to 125˚C or whose endpoints are measured at 30˚C and −25˚C for the range of 30˚C to −25˚.
Note 12: Offset Error calibration should be done at 30˚C. The residual error of the transfer function is then equivalent to the Accuracy Limit minus the Offset Limit.
This does not take into account the power supply sensitivity of the offset error. Nor, does it take into account the error introduced by the calibration system used.
