Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed.
Categories include technical documents, support and community resources, tools and software, and quick access to sample or buy. Heating will then be proportional to. Compensates for both sensor and resistor tolerances 1.
For other conditions, self heating must be considered. A pot connected across the LM with the arm tied to the adjustment terminal as shown in Figure 12 allows dztasheet 1-point calibration of the sensor that corrects for inaccuracy over the full temperature range. Operating Free-air Temperature Range 1.

If air temperature is targeted for measurement ensure that the PCB surface temperature datashfet close to the air temperature. Unlike other sensors, the. Information furnished is believed to be accurate and reliable.
Remove short across thermocouple. Samples may or may not be available. Product device recommended for new designs. Output Voltage Temperature Drift. Optocouplers – Texas Instruments. Pin Configuration and Functions Precautions should be taken to ensure good sens. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
C over a ? TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
Thermal Time Constant Figure 9. As in the case of all temperatures. Couple D2 to battery. Information of third fatasheet may be subject to additional restrictions. 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.
Datasheet of LM135, LM235, LM335-Precision Temperature Sensors
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. The influence of these currents on the minimum and maximum reverse current flowing through the LM should be calculated and be maintained in the range of 0. This is possible if the device is run with a temperature-stable current. 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.

Cable Connected Temperature Sensor Table 2. Finish options are separated by a vertical ruled line. Where designed to be soldered at high temperatures, Datasneet Pb-Free products are suitable for use in specified lead-free processes. Inside this datasheet the reader can find info related to ratings, precision temperature sensors, dynamic impedance, diagram, output voltage, The circuit has a daasheet impedance of less than.
Customers should validate and test their design implementation to confirm system functionality. Wide Operating Supply Figure Home About Contact Us.
Additional error can be introduced by varying load currents or varying supply voltage. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Select R3 and R4 for thermocouple type 2. Leave a Reply Cancel reply Your email address will not be published. This glossary lists and explains terms, acronyms, and definitions.
QoS assessment for mobile speech services hands-free communication. If the sensor is used in an ambient where the thermal resistance is constant, self-heating errors can be calibrated out.
Response Time Figure 5. Accuracy measurements satasheet made in a well-stirred oil bath. For optimum accuracy, a one point calibration is recommended. Your email address will not be published. No TI components are authorized datashee use in FDA Class III or similar life-critical medical equipment dattasheet authorized officers of the parties have executed a special agreement specifically governing such use.
Many explanation regarding sensors, compensation, thermocouple, and output voltage are described inside this datasheet. The LM should be operated at the lowest current suitable for the application. Soldering process must comply with the Reflow Temperature Profile specifications. Like any temperature-sensing device, selfheating can reduce accuracy.
