The LM61 is a precision integrated-circuit temperature sensor that can sense a −30°C to +100°C temperature range while operating from a single +2.7V supply. The LM61's output voltage is linearly proportional to Celsius (Centigrade) 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 ±2.0°C at room temperature and ±3°C over the full −25°C to +85°C temperature range.
The LM61's linear output, +600 mV offset, and factory calibration simplify external circuitry required in a single supply environment where reading negative temperatures is required.
