There is a confirmation about the concept of the calculation formula of the temperature sensor.
The data sheet (SNLS604) has the following wording
-------------------------------------------------- -------------------------------------------------- -
Note
Accuracy of temperature sensor can be maximized (3degreeC for temperature <105C and 7.5
degreeC for temperature> 105C), if customer can sample "temperature_output_code" at 25C
and use it as "temperature_output_mean_code".
-------------------------------------------------- -------------------------------------------------- ---
Is there any problem with the above wording in the following example?
One case
Ambient temperature: 25 ° C
reg_add: 047b
read_data: 5d00
[0x047B] [14:7] for selected sensor's output code: BA (hex) → 186 (dec)
temperature_calculated = 25 + (temperature_output_code -temperature_output_mean_code) * slope_temperature_sensor
temperature_calculated = 25 + (temperature_output_code -161) * 1.5
Change the formula of to use as follows.
temperature_calculated = 25 + (temperature_output_code -186) * 1.5
thanks!
