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.
