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.
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.
