LMT90EVM

The LMT90EVM evaluation module helps the designers to evaluate the operation and performance of the LMT90 analog temperature sensor. The LMT90 is a precision integrated circuit temperature sensor that can sense a -40°C to +125°C temperature range using a single positive supply. The LMT90s output voltage 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°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.
