Other Parts Discussed in Thread: TMP117
Hi,
I've made a comparizon between TMP117 and TMP114 specifications.
Both are base on a internal thermal BJT and have a 16 bits converter leading to a resolution of 0.007 °C
TMP117 accuracy is +/-0.15°C between -40°C and +70°C
TMP114 accuracy is +/-0.3°C between -10°C and 85°C
Accuracy curves look so close.
How comes this difference ?
Are they from different technologies ?
Is there a effect due to the packaging or heath exchange?
Are the accuracy tests conducted in a different way ?
Is the TMP117 trimed, not the TMP114 ?
Once we do a calibration of our own, piece by piece, shall we expect any difference of performance ?
Thank you.
Yours,
André
