3 Description

The LMT87 device 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 2.7-V

supply voltage operation, 5.4-μA quiescent current,

and 0.7-ms power-on time enable effective powercycling

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 offboard

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.

For devices with different average sensor gains and

comparable accuracy, refer to Comparable

Alternative Devices for alternative devices in the

LMT8x family.
