Devices are production tested at T
Guaranteed by design or characterization.
The offset and gain errors are corrected by self-calibration. The calibration process requires measurement to be made at
the selected data rate. The calibration error is therefore in the order of peak-to-peak noise for the selected rate.
Eliminate drift errors by recalibration at the new temperature.
The gain error excludes reference error, offset error (unipolar), and zero error (bipolar).
Gain-error drift does not include unipolar offset drift or bipolar zero-error drift. It is effectively the drift of the part if zero-
scale error is removed.
These specs are obtained from characterization during design or from initial product evaluation. Not production tested or
guaranteed.
OUTA/B = +0.5V or +1.5V, SWA/B = +1.5V or +0.5V, T
Long-term stability is characterized using five to six parts. The bandgaps are turned on for 1000hrs at room temperature
with the parts running continuously. Daily measurements are taken and any obvious outlying data points are discarded.
and 2) the ADC reference voltage is exactly equal to 1.25V. Any variations to this known reference characteristic and volt-
age caused by temperature, loading, or power supply results in errors in the temperature measurement. The actual tem-
perature calculation is performed externally by the microcontroller (µC).
