TI LM50CIM3X/NOPB

The LM50 device is a precision analog temperature sensor that can measure temperatures from - 40℃ to 125℃ using a single positive supply. The output voltage of the device is linearly proportional to temperature (10mV / ℃) and has a DC offset of 500mV at 0℃. The offset allows reading negative temperatures without the need for a negative supply. The output voltage of the LM50 ranges from 100mV (at - 40℃) to 1.75V (at 125℃), simplifying analog- to- digital converter (ADC) interfacing.

Unlike NTC thermistors, LM50 does not require any external calibration, trimming or software linearization leading to simplifying the circuitry requirements in a single supply environment. Due to low quiescent current of LM50 (typically around 95μA), self- heating is limited to a very low 0.2℃ (in still air) and the device is designed for remote or battery- powered applications. Trimming and calibration of the LM50 at the wafer level provide long- term availability, low cost and consistent accuracy in two grades: LM50B (± 2℃ at 25℃, ± 3℃ over temperature range) and LM50C (± 3℃ at 25℃, ± 4℃ over temperature range).
