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:

Equation 1. TMP20 sbos466a_equation1.gif

where

  • the temperature (T) is in °C.

When solving for temperature, the equation is shown as Equation 2:

Equation 2. TMP20 10090823.png

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:

Equation 3. TMP20 sbos466a_equation2.gif

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:

Equation 4. TMP20 sbos466a_equation3.gif

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:

Equation 5. TMP20 sbos466a_equation4.gif

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.
