The datasheet presents discussion lj135 typical performance characteristics, package, precision, physical dimensions, remote temperature Inside the datasheet you can read information such as temperature sensor, range, temperature, ambient temperature, and precision temperature sensors. If the sensor is used in an ambient where the thermal resistance is constant, self-heating errors can be calibrated out. LM – LM. Inside this datasheet the reader can find info related to ratings, precision temperature sensors, dynamic impedance, diagram, output voltage, Remove short across thermocouple.



Select R3 and R4 for thermocouple type 2. The information provided on this page represents TI’s knowledge and belief as of the date that it is provided.

Cable Connected Temperature Sensor Table 2. No license is granted by implication or otherwise under any patent or patent rights of STMicroelectronics. Heating will then be proportional to.

They operate as a 2-terminal Zener and datashete break. In some cases, TI components may be promoted specifically to facilitate safety-related applications. Device is in production to support existing customers, but TI does not recommend using this part in a new design.

Centigrade Calibrated Thermocouple Thermometer Figure Efficient temperature transfer assumes that the ambient air temperature is almost datasheer same as the surface temperature where the LM leads are attached. 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 LMA, for example. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions.


Adjust R1 for the voltage across R3 equal to the Seebeck Coefficient times ambient temperature in degrees Kelvin. Information furnished is believed to be accurate and reliable.

Datasheet – Texas Instruments

The LM should be datasheeet at the lowest current suitable for the application. Heating will then be proportional to zener voltage and therefore temperature.

The output of the device calibrated or uncalibrated can be expressed as: For other conditions, self heating must be considered.

This data is subject to change without notice and revision of this document. Important Information and Disclaimer: Thus a calibration of the. Efforts are underway to better integrate information from third parties.


Many explanation regarding sensors, compensation, thermocouple, and output voltage are described inside this datasheet. 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.

This datasheet contains information related to package information, voltage, cold junction compensation, calibration, precision temperature s Couple D2 to battery. 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.

Additional error can be introduced by varying load currents or varying supply voltage. TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

To insure that the temperature of the LM die is not affected by the air temperature, mechanically connect the LM leads with a bead of epoxy to the surface being measured.
