I apologize for asking this question because a similar questions has been asked before (https://e2e.ti.com/support/sensors/f/1023/t/216617?tisearch=e2e-sitesearch&keymatch=tmp275)
The only part of the temperature error that is clear is that the guaranteed maximum error from the true temperature is +/- 0.5 degrees. But then again.....I see numbers in the table below stating +/- 1.5 degrees in the range 25-100 degrees C at V+ 3.3 to 5.5 V?
Furthermore the repeatability (the precision) is only mentioned one place and thus also quite clear. I would like to know whether the repeatability stated is within 1 or 2 standard deviation(s)?
What accuracy that can be expected is quite confusing (accuracy defined as the proximity of measurement results to the true value). The TYP (typical) accuracy (temperature error) given in this table. What is it referring to? Is it the accuracy from the true temperature at the factory calibration at the given test conditions that can be expected for most (95% ?) of the shipped units?
Is it correct that the following figures also shows what typically can be expected? How does this related to the numbers in the above table? The table states a typical accuracy of +/- 0,0625 degrees, but the figure show roughly +/- 0,125 degrees accuracy. Can you please explain this.
Basically I need a better understanding of the accuracy and the precision of the temperature sensor.
- Is the stated precision within 1 or 2 standard deviations?
- For what percentage of the shipped units can the typical stated accuracy be expected? Definition of typical?
- What is the typical accuracy at room temperature?
Definition: Accuracy is the proximity of measurement results to the true value; precision, the repeatability, or reproducibility of the measurement
