The LMT70A is an ultra-small, high-precision, low-power CMOS analog temperature sensor with an output enable pin and temperature matching performance of max 0.1°C for two adjacent LMT70As that picked from the same reel. Applications for the LMT70 include virtually any type of temperature sensing where cost-effective, high precision and low-power are required, such as Internet of Things (IoT) sensor nodes, medical thermometers, high-precision instrumentation and battery powered devices. The LMT70A is also a great replacement for RTD and precision NTC/PTC thermistors and an ideal solution for energy metering applications requiring heat transfer calculations.
