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.
