The LMT70YFQR of Texas Instruments is a high-precision and low-power CMOS analog temperature sensor. Comes with an ultra-small size of 4DSBGA package, it features a output enable pin which allow multiple LMT70s to share one ADC channel so that simplifying ADC calibration and reducing the overall system cost for precision temperature sensing. It is also a great replacement for RTD and precision NTC/PTC thermistors.

It has ultra-low self-heating supporting its high-precision over a wide temperature range from -55°C to 150°C, makes it suitable for virtually any type of temperature sensing where cost-effective, high precision and low-power are required. Applications include internet of things (loT) sensor nodes, medical thermometers, high-precision instrumentation and battery powered devices.
