LM50

SOT-23 Single-Supply Centigrade Temperature Sensor

General Description

Applications

n Computers

The LM50 is a precision integrated-circuit temperature sen-

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

using a single positive supply. The LM50’s output voltage is

linearly proportional to Celsius (Centigrade) temperature

(+10 mV/˚C) and has a DC offset of +500 mV. The offset

allows reading negative temperatures without the need for a

negative supply. The ideal output voltage of the LM50 ranges

from +100 mV to +1.75V for a −40˚C to +125˚C temperature

range. The LM50 does not require any external calibration or

trimming to provide accuracies of 3˚C at room temperature

and 4˚C over the full −40˚C to +125˚C temperature range.

Trimming and calibration of the LM50 at the wafer level

assure low cost and high accuracy. The LM50’s linear out-

put, +500 mV offset, and factory calibration simplify circuitry

required in a single supply environment where reading nega-

tive temperatures is required. Because the LM50’s quiescent

current is less than 130 µA, self-heating is limited to a very

low 0.2˚C in still air.
