The host can query the LM73 at any time to read temperature.
Available in a 6-pin SOT package, the LM73 occupies very little board area while operating over a wide temperature range (–40°C to 150°C) and providing ±1°C accuracy from –10°C to 80°C.
The user can optimize between the conversion time and the sensitivity of the LM73 by programming it to report temperature in any of four different resolutions.
Defaulting to 11-bit mode (0.
25°C/LSB), the LM...
