The LMT90 device is a precision integrated-circuit temperature sensor that can sense a −40°C to +125°C temperature range using a single positive supply. The output voltage of LMT90 is linearly proportional to Celsius (Centigrade) temperature (10 mV/°C) and has a DC offset of 500 mV. The offset allows reading negative temperatures without the need for a negative supply. The ideal output voltage of the LMT90 ranges from 100 mV to 1.75 V for a −40°C to 125°C temperature range. The LMT90 does not require any external calibration or trimming to provide accuracies of ±3°C at room temperature and ±4°C over the full −40°C to +125°C temperature range. Trimming and calibration of the LMT90 at the wafer level assure low cost and high accuracy. The linear output, 500-mV offset, and factory calibration of LMT90 simplify circuitry required in a single-supply environment where reading negative temperatures is required. The LMT90’s quiescent current is less than 130 µA, thus self-heating is limited to a very low 0.2°C in still air.

The LMT90 is a cost-competitive alternative to thermistors.
