The Temperature Sensor transfer function is shown in Figure 6.2. The output voltage (V
input when the Temperature Sensor is selected by bits AMX0AD3-0 in register AMX0SL; this voltage will
be amplified by the PGA according to the user-programmed PGA settings. Typical values for the Slope and
Offset parameters can be found in Table 6.1.
