This is 3rd release (17/9) of LMT70 breakout board. The pins are compatible with 1st and 2nd releases and the same board size with the following improvements: thermal pads/vias Che Ni/Au ENIG surface finish red/yellow silk prints 1.2mm PCB thickness 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. Features: Accuracy: ±0.05°C (typ) or ±0.13°C (max) from 20°C to 42°C ±0.2°C (max) from -20°C to 90°C ±0.23°C (max) from 90°C to 110°C ±0.36°C (max) from -55°C to 150°C Wide Temperature Range: −55°C to 150°C Very Linear Analog Temperature Sensor NTC Output Slope: -5.19 mV/°C Output On/Off Switch with RDS on < 80 Ω Wide Power Supply Range: 2.0 V to 5.5 V Low Power Supply Current: 9.2 µA (typ) 12 µA (max) Technical details: Mfr. Part No.: Texas Instruments LMT70 (http://www.ti.com/product/LMT70) As far as today, this is our smallest breakout with a smallest component (<1mm) placed on the board: Ultra Small 0.88 mm by 0.88 mm 4-bump WLCSP (DSBGA) Designed and Assembled in London, UK
