The Temperature Sensor transfer function is shown in Figure 6.2. The output voltage (V_TEMP) is the PGA
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.
Slope (V / deg C)
Offset (V at 0 Celsius)
V_TEMP = (Slope x Temp_C) + Offset
Temp_C = (V_TEMP - Offset) / Slope
