The LMT85QDCKRQ1 is aprecision CMOS temperature sensor with ±0.4°C typical accuracy (±2.7°C maximum) and a linear analogoutput voltage that is inversely proportional to temperature. The 1.8-Vsupply voltage operation, 5.4-μA quiescent current, and 0.7-ms power-on time enable effectivepower-cycling architectures to minimize power consumption for battery-powered applications such asdrones and sensor nodes. The LMT85QDCKRQ1 device isAEC-Q100 Grade 0 qualified and maintains ±2.7°C maximum accuracy over the full operatingtemperature range without calibration; this makes the LMT85QDCKRQ1 suitable forautomotive applications such as infotainment, cluster, and powertrain systems. The accuracyover the wide operating range and other features make the LMT85QDCKRQ1 an excellent alternative to thermistors.
