where, T is the temperature in C; ADC is the 10-bit compensated ADC value; and TSCAL
is the temperature sensor calibration value, ignoring the two least significant bits of the
12-bit value.
See
Temperature Sensor Calibration Data
on page 164 for the location of TSCAL.
Calibration
The temperature sensor undergoes calibration during the manufacturing process and is
maximally accurate at 30 °C. Accuracy decreases as measured temperatures move further
from the calibration point.
