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. Temp Drift applies only if ambient is greater than ±10 °C of previous external calibration.
