2.2V-Capable, 10 uA Analog Output Temperature Sensor in SC70 and TO-92 - LMT86

LMT86 (ACTIVE)

2.2V-Capable, 10 uA Analog Output Temperature Sensor in SC70 and TO-92

 

Description

The LMT86 and LMT86-Q1 are precision CMOS temperature sensors with ±0.4°C typical accuracy (±2.7°C max) 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 LMT86-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 suitable for automotive applications such as infotainment, cluster, and powertrain systems. The accuracy over the wide operating range and other features make the LMT86 and LMT86-Q1 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.
