The output voltage of the LM61 is linearly proportional to temperature (10 mV/°C) and has a DC offset of 600 mV. The offset allows reading negative temperatures without the need for a negative supply. The nominal output voltage of the LM61 ranges from 300 mV to 1600 mV for a –30°C to 100°C temperature range. The LM61 is calibrated to provide accuracies of ±2°C at room temperature and ±3°C over the full –25°C to 85°C temperature range. The linear output of the LM61, 600-...
