*1) This is a reference value used for internal temperature compensation. We provide no guarantee that the value gives an
absolute value of the internal temperature.
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.
