Note: Accuracies are valid for measurements following an internal calibration.
Averaged numbers assume dithering and averaging of 100 single-channel
readings. Measurement accuracies are listed for operational temperatures within
±1°C of internal calibration temperature and ±10°C of external or factory
calibration temperature.
