DESCRIPTION
The LM135 series are precision, easily-calibrated, integrated circuit temperature sensors. Operating as a 2-
terminal zener, the LM135 has a breakdown voltage directly proportional to absolute temperature at +10 mV/°K.
With less than 1Ω dynamic impedance the device operates over a current range of 400 μA to 5 mA with virtually
no change in performance. When calibrated at 25°C the LM135 has typically less than 1°C error over a 100°C
temperature range. Unlike other sensors the LM135 has a linear output.
Applications for the LM135 include almost any type of temperature sensing over a −55°C to 150°C temperature
range. The low impedance and linear output make interfacing to readout or control circuitry especially easy.
The LM135 operates over a −55°C to 150°C temperature range while the LM235 operates over a −40°C to
125°C temperature range. The LM335 operates from −40°C to 100°C. The LM135/LM235/LM335 are available
packaged in hermetic TO transistor packages while the LM335 is also available in plastic TO-92 packages.
Schematic Diagram
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

APPLICATION INFORMATION
CALIBRATING THE LM135
Included on the LM135 chip is an easy method of calibrating the device for higher accuracies. A pot connected
across the LM135 with the arm tied to the adjustment terminal allows a 1-point calibration of the sensor that
corrects for inaccuracy over the full temperature range.
This single point calibration works because the output of the LM135 is proportional to absolute temperature with
the extrapolated output of sensor going to 0V output at 0°K (−273.15°C). Errors in output voltage versus
temperature are only slope (or scale factor) errors so a slope calibration at one temperature corrects at all
temperatures.
The output of the device (calibrated or uncalibrated) can be expressed as:
(1)
where T is the unknown temperature and To is a reference temperature, both expressed in degrees Kelvin. By
calibrating the output to read correctly at one temperature the output at all temperatures is correct. Nominally the
output is calibrated at 10 mV/°K.
To insure good sensing accuracy several precautions must be taken. Like any temperature sensing device, self
heating can reduce accuracy. The LM135 should be operated at the lowest current suitable for the application.
Sufficient current, of course, must be available to drive both the sensor and the calibration pot at the maximum
operating temperature as well as any external loads.
If the sensor is used in an ambient where the thermal resistance is constant, self heating errors can be calibrated
out. This is possible if the device is run with a temperature stable current. Heating will then be proportional to
zener voltage and therefore temperature. This makes the self heating error proportional to absolute temperature
the same as scale factor errors.
WATERPROOFING SENSORS
Meltable inner core heat shrinkable tubing such as manufactured by Raychem can be used to make low-cost
waterproof sensors. The LM335 is inserted into the tubing about ½″ from the end and the tubing heated above
the melting point of the core. The unfilled ½″ end melts and provides a seal over the device.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
