LMT01LPG Temperature Sensor: Pinout, Specification, and Datasheet

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 achieves flat ±0.5°C accuracy with very fine resolution (0.0625°C) over a wide temperature range of -20°C to 90°C without system calibration or hardware/software compensation.

Unlike other digital IC temperature sensors, LMT01’s single wire interface is designed to directly interface with a GPIO or comparator input, thereby simplifying hardware implementation. Similarly, the LMT01's integrated EMI suppression and simple 2-pin architecture make it ideal for on-board and off-board temperature sensing. The LMT01 offers all the simplicity of analog NTC or PTC thermistors with the added benefits of a digital interface, wide specified performance, EMI immunity, and minimum processor resources.
