*1) This is a reference value used for internal temperature compensation. There is no guarantee that the value gives an absolute value
of the internal temperature.
*2) This is the temperature scale factor for the upper 16bit (TEMP_HIGH).
Note) The values in the specifications are based on the data calibrated at the factory. The values may change according to the way the
product is used.
Note) The Typ values in the specifications are average values or 1σ values.
Note) Unless otherwise noted, the Max / Min values in the specifications are design values or Max / Min values at the factory tests.
