LM61 General Description


The LM61 is a precision integrated-circuit temperature sensor that can sense a -30 to +100 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 to +100 temperature range. The LM61 is calibrated to provide accuracies of ±2.0 at room temperature and ±3 over the full -25 to +85 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. Because the LM61's quiescent current is less than 125 µA, self-heating is limited to a very low 0.2 in still air. Shutdown capability for the LM61 is intrinsic because its inherent low power consumption allows it to be powered directly from the output of many logic gates.
