LM50
SOT-23 Single-Supply Centigrade Temperature Sensor
General Description
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
and
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.
