TMP100 max operating temp vs max measured temp?

Hi all,

Yes, this has been addressed offline so Mayrim, no further action is needed. Thanks everyone for the help, it is much appreciated!

For the sake of reference, the answer was:
There is room outside the -55 to 125C range in which the device will still function. The output register value can continue to rise past 125C or decrease past -55C, and it will saturate at the x7FF when temperatures exceed 128 deg C. So you could trigger an out of range error when any value not between -55 and 125C is read from the temperature register. Additionally, since the device essentially monotonically converts an analog temperature signal into a digital value, we would expect the output to stay ‘pegged’ to x7FF as the temperature increases past 128C. It should not give ‘garbage’ outputs (such as values that appear to be valid) until silicon breakdown occurs, which is at much, much, higher temperatures, and by then, the device will have already outputted x7FF so that an error can be triggered. Also note that as the device nears or exceeds the listed operating thresholds, the device accuracy will decrease (from +/-2C from -25 to 85 to +/-3C from -55 to 125).

That being said, the functional operation of the device at conditions beyond those specified in the datasheet is not supported and we don’t warrant or guarantee the device under those circumstances. The device does meet the requirement of measuring temperatures from -55 to 125C as listed in the datasheet and the nature of the device is that it will function outside that range, but we have not qualified the device outside that range and are not liable for that.
