What is the accuracy for AD7792 internal temperature sensor without calibrartion? +-2 degree C or +-4 degree C

or any else?

 

Also the temperture sensor is the enviromental temperture or mostly the die temperture?

 

For the calibration, how the calibration factor is applied? For example , if the room temperture is 25 degreeC, and the mesurement is 23 degree c. the calibrartion factor should be 2 degreec puls applied to future measurements or 25/23 multiplication for future measurements.

 

Thanks,
