The LMT90DBZT is a precision Temperature Sensor that can sense a -40 to +125°C temperature range using a single positive supply. The output voltage of LMT90 is linearly proportional to Celsius (Centigrade) temperature (10mV/°C) and has a DC offset of 500mV. The offset allows reading negative temperatures without the need for a negative supply. The ideal output voltage of the LMT90 ranges from 100mV to 1.75V for a -40 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 to +125°C temperature range. Trimming and calibration of the LMT90 at the wafer level assure low cost and high accuracy. The linear output, 500mV offset and factory calibration of LMT90 simplify circuitry required in a single-supply environment where reading negative temperatures is required.
