Texas Instruments LMT01/LMT01-Q1 2-Pin Temperature Sensor
Texas Instruments LMT01/LMT01-Q1 2-Pin Temperature Sensor is a high-accuracy, temperature sensor with an easy-to-use pulse count interface which makes it an ideal digital replacement for PTC or NTC thermistors. These are ideal for both on and off the board in automotive, industrial, and consumer markets. The LMT01/LMT01-Q1 digital pulse count output and high accuracy over a wide temperature range allow pairing with any MCU. This can be done without concern for integrated ADC quality or availability while minimizing software overhead. The LMT01/LMT01-Q1 achieves flat ±0.5°C accuracy with very fine resolution (0.0625°C) over a wide temperature range of -20°C to 90°C without system calibration or hardware/software compensation. The LMT01-Q1 devices are AEC-Q100 qualified for automotive applications.
