Description
The LMT87 device is a precision CMOS temperature sensor with andplusmn;0.4anddeg;C typical accuracy (andplusmn;2.7anddeg;C maximum) and a linear analog output voltage that is inversely proportional to temperature. The 2.7-V supply voltage operation, 5.4-andmu;A 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 LMT87LPG through-hole TO-92S package fast thermal time constant supports off board time-temperature sensitive applications such as smoke and heat detectors. The accuracy over the wide operating range and other features make the LMT87 an excellent alternative to thermistors.
