The datasheet for this device states that the accuracy is +/- 10 degrees Celsius. Is this true if the internal calibration constants are used or can you obtain a better accuracy when using the internal calibration parameters?
These internal sensors are typically quite imprecise, thus +/-10 °C is valid even it is calibrated in accordance to reference manual. Of course accuracy will be better than +/-10 °C as these values are corner cases.
