ClosedCube LMT70 ±0.1°C Precision Analog Temperature Sensor Breakout

This is 2nd release (16/2) of LMT70 breakout board. The pins are compatible with 1st release and the same board size with the following improvements:

• 0402 C1/C2 capacitors
• thermal pads/vias
• Che Ni/Au ENIG surface finish

The LMT70 is an ultra-small, high-precision and low-power CMOS analog temperature sensor. 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 LMT70 is also a great replacement for RTD and precision NTC/PTC thermistors.
