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 with a GPIO or comparator input, thereby simplifying
hardware implementation. Similarly, the LMT01s integrated EMI
suppression and simple 2-pin architecture makes it suitable for onboard and offboard temperature
sensing in a noisy environment. The LMT01 device can be easily
converted into a two-wire temperature probe with a wire length up to two meters. See LMT01-Q1 for the
automotive qualified version.
