Note 1:
Note 2: Guaranteed by design or characterization.
Note 3: The offset and gain errors are corrected by self-calibration or system calibration. For accurate calibrations, perform cali-
Note 4: Eliminate drift errors by recalibration at the new temperature.
Note 5: The gain error excludes reference error, offset error (unipolar), and zero error (bipolar).
Note 6: Gain-error drift does not include unipolar-offset drift or bipolar zero-error drift. It is effectively the drift of the part if zero-
Note 7: These specifications are obtained from characterization during design or from initial product evaluation. Not production
Note 8: V
Note 9: Long-term stability is characterized using five to six parts. The bandgaps are turned on for 1000hrs at room temperature
Note 10: Temperature error is the difference in the calculated temperature using the internal circuit vs. measurements made using
Note 11: All the stated temperature accuracies assume that 1) the external diode characteristic is precisely known (i.e., ideal) and
Note 12: Values based on simulation results and are not production tested or guaranteed.

2) the ADC reference voltage is exactly equal to 1.25V. Any variations to this known reference characteristic and voltage
caused by temperature, loading, or power supply results in errors in the temperature measurement. The actual tempera-
ture calculation is performed externally by the µC.
