One can see that the temperature measurement accu-

racy depends directly on . So the voltage on

the pin must be stable.

The output signal from thermistor scheme depends on

its resistance as :

–40 –20 0 20 40

Temperature, °C

Output, V

With the help of equations (3.1) and (3.2) we obtain the

plot in Fig. 3.24.
