7‑V supply.
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-mV 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.
