Texas Instruments  LMT01DQXT

The LMT01 device is a high-accuracy, 2-pin temperature sensor with aneasy-to-use pulse count current loop interface, which makes it suitable for onboard and offboardapplications in automotive, industrial, and consumer markets. The LMT01 digital pulse count output and high accuracy over a widetemperature range allow pairing with any MCU without concern for integrated ADC quality oravailability, while minimizing software overhead. TI’s LMT01 device achieves amaximum ±0.5°C accuracy with very fine resolution (0.0625°C) over a temperature range of –20°C to90°C without system calibration or hardware and software compensation.

The LMT01’s pulse countinterface is designed to directly interface with a GPIO or comparator input, thereby simplifyinghardware implementation. Similarly, the LMT01’s integrated EMIsuppression and simple 2-pin architecture makes it suitable for onboard and offboard temperaturesensing in a noisy environment. The LMT01 device can be easilyconverted into a two-wire temperature probe with a wire length up to two meters. See LMT01-Q1 for theautomotive qualified version.
