Description

Description
The LM35 series are precision integrated-circuit
temperature devices with an output voltage linearlyproportional
to the Centigrade temperature. The
LM35 device has an advantage over linear
temperature sensors calibrated in Kelvin, as the user
is not required to subtract a large constant voltage
from the output to obtain convenient Centigrade
scaling. The LM35 device does not require any
external calibration or trimming to provide typical
accuracies of ±¼°C at room temperature and ±¾°C
over a full −55°C to 150°C temperature range. Lower
cost is assured by trimming and calibration at the
wafer level. The low-output impedance, linear output,
and precise inherent calibration of the LM35 device
makes interfacing to readout or control circuitry
especially easy. The device is used with single power
supplies, or with plus and minus supplies. As the
LM35 device draws only 60 μA from the supply, it has
very low self-heating of less than 0.1°C in still air. The
LM35 device is rated to operate over a −55°C to
150°C temperature range, while the LM35C device is
rated for a −40°C to 110°C range (−10° with
improved accuracy). The LM35-series devices are
available packaged in hermetic TO transistor
packages, while the LM35C, LM35CA, and LM35D
devices are available in the plastic TO-92 transistor
package. The LM35D device is available in an 8-lead
surface-mount small-outline package and a plastic
TO-220 package.
