3 Description

The LMT86-Q1 are precision CMOS temperature

sensors with ±0.4°C typical accuracy (±2.7°C

maximum) and a linear analog output voltage that

is inversely proportional to temperature. The 2.2-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 LMT86-Q1-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

LMT86-Q1-Q1 suitable for automotive applications

such as infotainment, cluster, and powertrain systems.

The accuracy over the wide operating range and other

features make the LMT86-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.
