Product Summary

The LM73CIMKX-0 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 LM73CIMKX-0 at any time to read temperature. Available in a 6-pin SOT-23 package, the LM73CIMKX-0 occupies very little board area while operating over a wide temperature range (-40℃ to 150℃) and providing ±1.0℃ accuracy from -10℃ to 80℃. 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. The applications of the LM73CIMKX-0 are Portable Electronics, Notebook Computers, Automotive, System Thermal Management, Office Electronics.
