LM73,datasheet,pdf(11-to-14 Bi

The LM73 is an integrated, digital-output temperature sensor
featuring an incremental Delta-Sigma ADC with a two-wire
interface that is compatible with the SMBus and I2C® interfaces.
The host can query the LM73 at any time to read
temperature. Available in a 6-pin SOT-23 package, the LM73
occupies very little board area while operating over a wide
temperature range (-40°C to 150°C) and providing ±1.0°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
LM73 measures temperature in a maximum time of 14 ms,
making it ideal for applications that require temperature data
very soon after power-up. In its maximum resolution, 14-bit
mode (0.03125°C/LSB), the LM73 is optimized to sense very
small changes in temperature.
