LM50BLM50C
SOT-23 Single-Supply Centigrade Temperature Sensor
General Description
The LM50 is a precision integrated-circuit temperature sen-
sor that can sense a b40 Cto a125 C temperature range
using a single positive supply The LM50’s output voltage is
linearly proportional to Celsius (Centigrade) temperature
(a10 mV C) and has a DC offset of a500 mV The offset
allows reading negative temperatures without the need for a
negative supply The ideal output voltage of the LM50
ranges from a100 mV to a175V for a b40 Cto a125 C
temperature range The LM50 does not require any external
calibration or trimming to provide accuracies of g3 Cat
room temperature and g4 C over the full b40 Cto
a
125 C temperature range Trimming and calibration of the
LM50 at the wafer level assure low cost and high accuracy
The LM50’s linear output a500 mV offset and factory cali-
bration simplify circuitry required in a single supply environ-
ment where reading negative temperatures is required Be-
cause the LM50’s quiescent current is less than 130 mA
self-heating is limited to a very low 02 C in still air
