LM60

2.7V, SOT-23 or TO-92 Temperature Sensor

General Description

The LM60 is a precision integrated-circuit temperature sen-

sor that can sense a −40˚C to +125˚C temperature range

while operating from a single +2.7V supply. The LM60’s

output voltage is linearly proportional to Celsius (Centigrade)

temperature (+6.25 mV/˚C) and has a DC offset of +424 mV.

The offset allows reading negative temperatures without the

need for a negative supply. The nominal output voltage of the

LM60 ranges from +174 mV to +1205 mV for a −40˚C to

+125˚C temperature range. The LM60 is calibrated to pro-

vide accuracies of

over the full −25˚C to +125˚C temperature range.

The LM60’s linear output, +424 mV offset, and factory cali-

bration simplify external circuitry required in a single supply

environment where reading negative temperatures is re-

quired. Because the LM60’s quiescent current is less than

110 µA, self-heating is limited to a very low 0.1˚C in still air in

the SOT-23 package. Shutdown capability for the LM60 is

intrinsic because its inherent low power consumption allows

it to be powered directly from the output of many logic gates.
