NOTES: 1. Not production tested, limits characterized.
2. The following formula can be used to calculate the temperature sensor output voltage:
V_Sensor,typ = TC_Sensor ( 273 + T [°C] ) + V_{Offset,sensor} [mV]
3. Results based on characterization and/or production test, not TC_Sensor or V_{Offset,sensor}.
