Temperature Output Register
The offset of temperature sensor is factory calibrated but sensitivity of the temperature data varies
from part to part. The temperature doesn't reflect absolute ambient temperature.
Temperature data is in 2's complement format in 14 bits (15:2) of Temp register. To use the
temperature sensor as an absolute temperature sensor or for additional system level
compensations, the offset and sensitivity of the sensor should be measured and calibrated on
system level
Temperature registers’ typical output at +23 °C is -1755 counts and 1 °C change in temperature
typically corresponds to 65 count change in temperature sensor output. Temperature information
can be converted from decimals to [°C] as follows
where Temp[°C] is temperature in Celsius and Temp[LSB] is temperature from TEMP registers in
decimal format,
Temperature sensor offset calibration error at 25°C: ≤ ±15 °C
Temperature sensor sensitivity calibration error : ≤ 5%
