7.3.1 Transfer Function
The analog output of the TMP20 over the –55°C to +130°C temperature range corresponds to the parabolic transfer function shown in Equation 1:
where
- the temperature (T) is in °C.
When solving for temperature, the equation is shown as Equation 2:
These equations apply over the entire operating range of –55°C to +130°C.
A simplified linear transfer function referenced at 25°C is shown in Equation 3:
Linear transfer functions are calculated for limited temperature ranges by calculating the slope and offset for that limited range, where slope is calculated by Equation 4:
where
- T equals the temperature at the middle of the temperature range of interest
The offset in the linear transfer function is calculated with Equation 5:
where
- VOUT(TMAX) is the calculated output voltage at TMAX as determined from Equation 1.
VOUT(T) is the calculated output voltage at T as calculated by Equation 1.
