3 Description
The LMT85 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 1.8-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 LMT85LPG through-hole TO-92S
package fast thermal time constant supports offboard
time-temperature sensitive applications such
as smoke and heat detectors. The accuracy over the
wide operating range and other features make the
LMT85 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.
