(1) The temperature sensor offset can vary significantly. TI recommends a single-point calibration to minimize the offset error of the built-in
temperature sensor.
(2) The device descriptor structure contains calibration values for 30°C ±3°C and 85°C ±3°C for each of the available reference voltage
levels. The sensor voltage can be computed as V_SENSE = TC_SENSOR × (Temperature, °C) + V_SENSOR, where TC_SENSOR and V_SENSOR can
be computed from the calibration values for higher accuracy.
(3) The typical equivalent impedance of the sensor is 700 kΩ. The sample time required includes the sensor-on time t_SENSOR(on).
