LM61 2.7V, SOT-23 or TO-92 Temperature Sensor
June 1999
LM61
2.7V, SOT-23 or TO-92 Temperature Sensor
General Description
The LM61 is a precision integrated-circuit temperature sen-
sor that can sense a 鈭?0藲C to +100藲C temperature range
while operating from a single +2.7V supply. The LM61鈥檚 out-
put voltage is linearly proportional to Celsius (Centigrade)
temperature (+10 mV/藲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 鈭?0藲C to
+100藲C temperature range. The LM61 is calibrated to pro-
vide accuracies of
鹵
2.0藲C at room temperature and
鹵
3藲C
over the full 鈭?5藲C to +85藲C temperature range.
The LM61鈥檚 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鈥檚 quiescent current is less than
125 碌A(chǔ), self-heating is limited to a very low 0.2藲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.
