Hi,
I had looked at using the LM75B however discovered that the temperature will not update when reading the last temperature. (see note 8 of datasheet)
I have now shortlisted the LM73 instead as there is no information that implies the same as in the LM75B.
Note 9 of LM73 datasheet states:
"This specification is provided only to indicate how often temperature data is updated. The LM73 can be read at any time without regard to conversion state (and will yield last conversion result)."
Am I correct in assuming then that the LM73 permits temperature to be read without interrupting the current conversion?
Many thanks
Ryan
Hi Ryan,
Yes, the LM73 has a different state machine and it just delays updating the output buffer instead of aborting the conversion in progress. That being said, you should be carefull about talking to these parts too often as bus trafic will cuase additional power dissipation and thus self heating and that additional errors.
Take care,
