Example 1

Determine the linear transfer function for –40°C to +110°C.

TMIN = –40°C; TMAX = 110°C; therefore, T = 35°C

m = –11.77mV/°C

VOUT (110°C) = 0.5520 V

VOUT (35°C) = 1.4566 V

b = 1.8576 V

The linear transfer function for –40°C to +110°C is shown in Equation 6:

Table 1 lists common temperature ranges of interest and the corresponding linear transfer functions for these ranges. Note that the error (maximum deviation) of the linear equation from the parabolic equation increases as the temperature ranges widen.

Table 1. Common Temperature Ranges and Corresponding Linear Transfer Functions

TEMPERATURE RANGE LINEAR EQUATION (V) MAXIMUM DEVIATION OF LINEAR EQUATION FROM PARABOLIC EQUATION (°C)
TMIN (°C) TMAX (°C)
–55 130 VOUT = –11.79 mV/°C × T + 1.8528 ±1.41
–40 110 VOUT = –11.77 mV/°C × T + 1.8577 ±0.93
–30 100 VOUT = –11.77 mV/°C × T + 1.8605 ±0.70
–40 85 VOUT = –11.67 mV/°C × T + 1.8583 ±0.65
–10 65 VOUT = –11.71 mV/°C × T + 1.8641 ±0.23
35 45 VOUT = –11.81 mV/°C × T + 1.8701 ±0.004
20 30 VOUT = –11.69 mV/°C × T + 1.8663 ±0.004
