Temperature Sensor

Z8 Encore! XP® F08xA Series

Product Specification

125

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.
