LMT86 - Analog Temperature Sensors

📥 Download Datasheet

General 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 2.2V supply voltage operation, 5.4μA quiescent current, and 0.7ms poweron 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 timetemperature sensitive applications such as smoke and heat detectors.
