The LMT84-Q1 is a precision CMOS temperature sensor with ±0.4°C typical accuracy (±2.7°C maximum) and a linear analog output voltage that is inversely proportional to temperature. The 1.5-V supply voltage operation, 5.4-µA quiescent current, and 0.7-ms power-on time enable effective power-cycling architectures to minimize power consumption for battery-powered applications such as drones and sensor nodes.The LMT84-Q1 device is AEC-Q100 Grade 0 qualified and maintains ±2.7°C maximum accuracy over the full operating temperature range without calibration; this makes the LMT84-Q1 suitable for automotive applications such as infotainment, cluster, and powertrain systems. The accuracy over the wide operating range and other features make the LMT84-Q1 an excellent alternative to thermistors.
For devices with different average sensor gains and comparable accuracy, refer to Comparable Alternative Devices for alternative devices in the LMT8x family.
