Typical Application
3 Description
The LM61 device is a precision, integrated-circuit temperature sensor that can sense a
- 30°C to 100°C temperature range while operating from a single 2.7‑V supply. The output voltage of the LM61 is linearly proportional to temperature (10 m V/°C) and has a DC offset of 600 m V. The offset allows reading negative temperatures without the need for a negative supply. The nominal output voltage of the LM61 ranges from 300 m V to 1600 m V 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-m V offset, and factory calibration simplify external circuitry required in a single supply environment where reading negative temperatures is required. Because the quiescent current is less than 125 µA, self-heating is limited to a very low 0.2°C 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.
