The LM50-Q1 device is an automotive-grade analog temperature sensor (AEC-Q100 Grade 1 qualified) that can measure temperatures from -40°C to 125°C using a single positive supply. The output voltage of the device is 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-Q1 ranges from 100mV (at –40°C) to 1.75V (at 125°C), simplifying automotive ADC interfacing (including ADC integrated in MCU).
Unlike NTC thermistors, LM50-Q1 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-Q1 (typically around 95µA), self-heating is limited to a very low 0.2°C (in still air) and the device is ideal for automotive applications such as ECUs. Trimming and calibration of LM50-Q1 at the wafer level verify low cost and consistent accuracy: (±3°C at 25°C, ±4°C across –40°C to 125°C). Functional safety documentation is also available for systems requiring enhanced reliability.
