Hi,
I'm a bit confused about what the +-0.1deg accuracy of the TMP117 realistically means. Is it an absolute accuracy? E.g. suppose there is an ideal sensor that measures the "real" temperature without any errors, the TMP117's results lands within +-0.1deg of that of the ideal sensor?
For my application I am only concerned with temperature change, not absolute temperature. Is my measurement noise floor then limited by this 0.1deg accuracy, or the 0.0078deg resolution, or somewhere in between? Within the same sensor, when the reading increases by 1 bit (0.0078deg), does that reflect a real temperature increase, or should it be treated as purely quantisation noise?
The above is all assuming 20-30deg temperature range, 8 averages, continuous cycle, 1Hz cycle time (basically the default configuration).
Thanks in advance,
Ya
