In the ADuC814 datasheet, it is mentioned that the internal temperature sensor
of ADuC8xx gives 650mV at 25C and that "is a voltage output ... which is
proportional to absolute temperature". What is the exact characteristic ?
Linear slope - but at how much mV per Celsius Degree ? Whats the minimum and
maximum Temperature to measure ?


The temperature sensor is not tested in production and the precise temperature
to voltage characteristic is subject to significant part-to-part variation
which we go not guarantee.

The best use of this sensor is to indicate that the temperature has changed,
rather than to make precise temperature measurements.
