150 C014 3 Description The LMT01 device is a high-accuracy, 2-pin temperature sensor with an easy-to-use pulse count current loop interface, which makes it suitable for onboard and offboard applications in automotive, industrial, and consumer markets.
The LMT01 digital pulse count output and high accuracy over a wide temperature range allow pairing with any MCU without concern for integrated ADC quality or availability, while minimizing software overhead.
TI’s LMT01 device achieves a maximum ±0.
5°C accuracy with very fine resolution (0.
0625°C) over a temperature range of –20°C to 90°C without system calibration or hardware and software compensation.
The LMT01’s pulse count interface is designed to directly interface...
