The LMT01-Q1 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-Q1 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-Q1 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-Q1’s pulse count
interface is designed to directly interface with a GPIO or comparator input, thereby simplifying
hardware implementation. Similarly, the LMT01-Q1s integrated EMI
suppression and simple 2-pin architecture makes it suitable for onboard and offboard temperature
sensing in a noisy environment. The LMT01-Q1 device can be easily
converted into a two-wire temperature probe with a wire length up to two meters.
