Note:
Accuracies are valid for analog output following an internal calibration. Analog output accuracies are
listed for operation temperatures within ±1 °C of internal calibration temperature and ±10 °C of external or
factory calibration temperature. Temperature drift applies only if ambient is greater than ±10 °C of previous
external calibration.
