LMx35, LMx35A Precision Temperature Sensors
1 Features
3 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 1-Ω 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
are 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 LMx35 devices
are available packaged in hermetic TO transistor
packages while the LM335 is also available in plastic
TO-92 packages.

7 Detailed Description
7.1 Overview
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.
Operating as a 2-terminal zener, the LM135 has a breakdown voltage directly proportional to absolute
temperature at 10 mV/°K. With less than 1-Ω 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.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Temperature Calibration Using ADJ Pin
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 (as shown in Figure 12) 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 0-V 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:

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
To insure good sensing accuracy, several precautions must be taken. Like any temperature-sensing device, selfheating 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.

8.2.2 Detailed Design Procedure
For optimum accuracy, R1 is picked such that 1 mA flows through the sensor. Additional error can be introduced
by varying load currents or varying supply voltage. The influence of these currents on the minimum and
maximum reverse current flowing through the LM135 should be calculated and be maintained in the range of 0.4
mA to 5 mA. Minimizing the current variation through the LM135 will provide for the best accuracy. The
Operating Output Voltage Change with Current specification can be used to calculate the additional error which
could be up to 1 K maximum from the LM135A, for example.

9 Power Supply Recommendations
Ensure the LM335 is biased properly with a current ranging 0.4 mA to 5 mA.
10 Layout
10.1 Layout Guidelines
The LM135 is applied easily in the same way as other integrated-circuit temperature sensors. Glue or cement the
device to a surface and the temperature should be within about 0.01°C of the surface temperature.
Efficient temperature transfer assumes that the ambient air temperature is almost the same as the surface
temperature where the LM135 leads are attached. If there is a great difference between the air temperature and
the surface temperature, the actual temperature of the LM135 die would be at an intermediate temperature
between the two temperatures. For example, the TO-92 plastic package, where the copper leads are the
principal thermal path to carry heat into the device, can be greatly affected by airflow. The temperature sensed
by the TO92 package could greatly depend on velocity of the airflow as well.
To lessen the affect of airflow, ensure that the wiring to the LM135 (leads and wires connected to the leads) is
held at the same temperature as the surface temperature that is targeted for measurement. To insure that the
temperature of the LM135 die is not affected by the air temperature, mechanically connect the LM135 leads with
a bead of epoxy to the surface being measured. If air temperature is targeted for measurement ensure that the
PCB surface temperature is close to the air temperature. Keep the LM135 away from offending PCB heat
sources such as power regulators. One method commonly used for thermal isolation is to route a thermal well as
shown in Figure 33 with the smallest possible geometry traces connecting back to rest of the PCB.

10.3 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 0.5 inches from the end and the tubing heated
above the melting point of the core. The unfilled 0.5-inch end melts and provides a seal over the device.
10.4 Mounting the Sensor at the End of a Cable
The main error due to a long wire is caused by the voltage drop across that wire caused by the reverse current
biasing the LM135 on. Table 2 shows the wire AWG and the length of wire that would cause 1°C error.

11.1.1 Device Nomenclature
Operating Output Voltage: The voltage appearing across the positive and negative terminals of the device at
specified conditions of operating temperature and current.
Uncalibrated Temperature Error: The error between the operating output voltage at 10 mV/°K and case
temperature at specified conditions of current and case temperature.
Calibrated Temperature Error: The error between operating output voltage and case temperature at 10 mV/°K
over a temperature range at a specified operating current with the 25°C error adjusted to zero.
