QThe output of the temperature sensor is different (quite a lot) than that is
mentioned in the datasheet for room temperature. May the sensor be broken down
or do I have to make calibration? If so, how?
AThe temperature sensor measures the die temperature, which is normally higher
than the ambient temperature. The temperature sensor is tested in production so
you shouldn't need to calibrate it yourself to obtain the correct temperature
within +/-3degC once you have accounted for the increase in temperature inside
the IC package.
