Description
-----------
The NTC thermistor is a simple thermistor that requires users to provide the
resistance and lookup the corresponding compensation table to get the
temperature input.
The NTC (Negative Temperature Coefficient) thermistor is a simple thermistor
that requires users to provide the resistance and lookup the corresponding
compensation table to get the temperature input.
The NTC driver provides lookup tables with a linear approximation function
and four circuit models with an option not to use any of the four models.
