TI LM73CIMK-0/NOPB

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 package, the LM73 occupies very little board area while operating over a wide temperature range (- 40℃ to 150℃) and providing ±1℃ accuracy from - 10℃ to 80℃. 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℃ / 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℃ / LSB), the LM73 is optimized to sense very small changes in temperature. A single multi- level address line selects one of three unique device addresses. An open- drain ALERT output goes active when the temperature exceeds a programmable limit. Both the data and clock lines are filtered for excellent noise tolerance and reliable communication. Additionally, a time- out feature on the clock and data lines causes the LM73 to automatically reset these lines if either is held low for an extended time, thus exiting any bus lock- up condition without processor intervention.
