temperature sensor
TOFFSET
ADC output at 0°C of the temperature sensor
1750
LSB
(1)
The temperature sensor slope and offset are given in terms of ADC LSBs using the internal reference of the ADC. Values must be
adjusted accordingly in external reference mode to the external reference voltage.
(2)
ADC temperature coeffieicient is accounted for in this specification
(3)
Output of the temperature sensor (in terms of LSBs) is sign-consistent with the direction of the temperature movement. Increasing
temperatures will give increasing ADC values relative to an initial value; decreasing temperatures will give decreasing ADC values
relative to an initial value.
