The following equation defines the transfer function between the temperature sensor out-
put voltage and the die temperature:
T = 100*V - 77 (where 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 - 77 (where T is the temperature in C; ADC is the 10 bit compensated
ADC value)
Calibration
The temperature sensor undergoes calibration during the manufacturing process and is
maximally accurate only at 30°C. Accuracy decreases as measured temperatures move
further from the calibration point.
Because this sensor is an on-chip sensor it is recommended that the user account for the
difference between ambient and die temperature when inferring ambient temperature con-
ditions.
