TI LMT01LPGM

The LMT01 is a high-accuracy two-pin temperature sensor with an easy-to-use pulse-count current-loop interface, making it suitable for on-board and off-board applications in automotive, industrial, and consumer markets. The LMT01 features a digital pulse-count output that delivers high accuracy over a wide temperature range, making it an ideal companion for any MCU — reducing software overhead without compromising the quality or availability of an integrated ADC. The LMT01 provides ±0.5°C maximum accuracy over the -20°C to 90°C temperature range with high resolution (0.0625°C), requiring no system calibration or software/hardware compensation. The LMT01's pulse-count interface is designed for direct connection to a GPIO or comparator input, simplifying hardware implementation. Likewise, the LMT01's integrated EMI suppression and simple two-pin architecture make it suitable for on-board and off-board temperature sensing in noisy environments. The LMT01 can easily be converted into a two-wire temperature probe with cable lengths up to two meters.
