LM73CIMK-0/NOPB Board Mount Temperature Sensors Programmable
Description
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 lttle 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 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.
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.
