The LM61 is a precision integrated-circuit temperature sen-

sor that can sense a −30˚C to +100˚C temperature range

while operating from a single +2.7V supply. The LM61’s out-

put 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 pro-

vide accuracies of 2.0˚C at room temperature and 3˚C

over the full −25˚C to +85˚C temperature range.

Key Specifications

The LM61’s linear output, +600 mV offset, and factory cali-

bration simplify external circuitry required in a single supply

environment where reading negative temperatures is re-

quired. Because the LM61’s 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 in-

herent low power consumption allows it to be powered di-

rectly from the output of many logic gates.
