3 Description
The LMT84-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 1.5-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 LMT84-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 LMT84-Q1 suitable
for automotive applications such as infotainment,
cluster, and powertrain systems. The accuracy over
the wide operating range and other features make the
LMT84-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.
