Lab 6 – ADC Temperature Sensor
Temperature Conversion
Temp = 25 - ((VTEMP -VTEMP25)
÷
m)
where:
— VTEMP is the voltage of the temperature sensor channel at the
ambient temperature.
— VTEMP25 is the voltage of the temperature sensor channel at 25°C.
— m is the hot or cold voltage versus temperature slope in V/°C.
Specified at 1.646 from -40 to 25C, 1.769 from 25 to 85C.
Temperature sensor accuracy is being characterized at the factory.
Application Note AN3031 will be published.
