3 Description

The LMT85-Q1 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 powercycling

architectures to minimize power consumption

for battery-powered applications such as drones and

sensor nodes. The LMT85-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 LMT85-Q1 suitable

for automotive applications such as infotainment,

cluster, and powertrain systems. The accuracy over

the wide operating range and other features make the

LMT85-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.
