Tool/software:
Hi team,
My customer would like to know what's the definition of accuracy of ±1°C for TMP114NAIYMTR?
Does it mean that the temp that TMP114N reports will deviate the accurate temp within ±1°C?
If the TMP114N was put in a stove with constant temp, will the temperautre that TMP114N reports stay the constanst? Or will it has small oscillation but the variance is within ±1°C?
Thanks.
Hi Nai-Wen,
Accuracy is defined as how close the temperature output of the device is with respect to the junction temperature. Meaning that if junction temperature is 25°C (given the setup conditions are met), then the temperature output will be within ±0.3°C since this is the maximum accuracy expected within the -10°C and 80°C range.
The second point that you are alluding to is defined as noise which is a different spec. Noise will be highly dependent on the configuration of the device since this device is capable of producing a 1-sample output or an average of 8 samples--in both cases at different conversion times. For more information on this, please refer to section 7.7 of the datasheet.
Where 1 LSB is the temperature resolution of the ADC: 0.0078°C.
Best regards,
Simon Rojas
