7.3.1 Transfer Function

The analog output of the TMP9A00-EP over the –55 °C to 150 °C temperature range corresponds to the parabolic transfer function shown in Equation 1:

Equation 1. GUID-1500E8BA-553D-4B5C-B2D3-57489B630139-low.gif

Where:

  • The temperature (T) is in °C.

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

Equation 2. GUID-E69C6510-0A7C-4E58-BAC1-EBC535ED940A-low.gif

These equations apply over the entire operating range of –55 °C to 150 °C.

A simplified linear transfer function referenced at 0 °C is shown in Equation 3:

Equation 3. GUID-8EDF500E-C8E6-4F94-97E6-8B2A870CBBDD-low.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. GUID-DA451E59-A59E-4C95-BFE1-7753E9430544-low.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. GUID-0333D8C0-8587-4BF6-9C25-0B8CE7CF9697-low.gif

where

  • VOUT(TMAX) is the calculated output voltage at TMAX.
