LMT86
SNIS169E – MARCH 2013 – REVISED OCTOBER 2017
LMT86 2.2-V, SC70/TO-92/TO-92S,
Analog Temperature Sensors
1 Features
1 LMT86LPG (TO-92S package) has a Fast
Thermal Time Constant, 10-s Typical (1.2 m/s
Airflow)
• Very Accurate: ±0.4°C Typical
• Low 2.2-V Operation
• Average Sensor Gain of -10.9 mV/°C
• Low 5.4-µA Quiescent Current
• Wide Temperature Range: –50°C to 150°C
• Output is Short-Circuit Protected
• Push-Pull Output With ±50-µA Drive Capability
• Footprint Compatible With the Industry-Standard
LM20/19 and LM35 Temperature Sensors
• Cost-Effective Alternative to Thermistors
2 Applications
• Infotainment and Cluster
• Powertrain Systems
• Smoke and Heat Detectors
• Drones
• Appliances
3 Description
The LMT86 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 LMT86LPG through-hole TO-92S
package fast thermal time constant supports off-
board time-temperature sensitive applications such
as smoke and heat detectors. The accuracy over the
wide operating range and other features make the
LMT86 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.
