In the above equation, T is the temperature in °C; V is the sensor output in volts.
Assuming a compensated ADC measurement, the following equation defines the relation-
ship between the ADC reading and the die temperature:
T = 25 128 ADC – TSCAL11:2 + 30
In the above equation, 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 sig-
nificant bits of the 12-bit value.
See the Temperature Sensor Calibration Data section on page 171 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.
