The LM50 and LM50HV devices are precision analog temperature sensors that can measure temperatures from -40°C to 125°C (for LM50) and -40°C to 150°C (for LM50HV) using a single positive supply. Unlike NTC thermistors, LM50 and LM50HV do not require any external calibration, trimming or software linearization leading to simplifying the circuitry requirements. The output voltage of the devices are linearly proportional to temperature (10mV/°C) and has a DC offset of 500mV at 0°C. The offset allows reading negative temperatures without the need for a negative supply. The output voltage of the LM50 and LM50HV ranges from 100mV (at -40°C) to 1.75V (at 125°C for LM50) and 2V (at 150°C for LM50HV), simplifying analog-to-digital converter (ADC) interfacing.

LM50HV is designed for LDO-less application due to stable functionality across wide supply range of 3V to 36V. Trimming and calibration of the LM50 and LM50HV at the wafer level provide long-term availability, low cost and consistent accuracy: LM50B (±3°C over temperature range), LM50C (±4°C over temperature range) and LM50HV (±3°C over -20°C to 150°C).
