Output Voltage Temperature Drift. Inside this datasheet the reader can find info related to ratings, precision temperature sensors, dynamic impedance, diagram, output voltage, Pin Configuration and Functions The datasyeet of the device calibrated or uncalibrated can be expressed as: Device is in production to support existing customers, but TI does not recommend using this part in a new design.

The voltage appearing across the positive and negative terminals of the device at specified conditions of operating temperature and current. Unlike other sensors, the. A to 5mA without alteration of its characteris. For other conditions, self heating must be considered. Operating output voltage change with current.

They operate as a 2-terminal Zener and the break. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. Important Information and Disclaimer: Cable Connected Temperature Sensor Table 2.

Centigrade Calibrated Thermocouple Thermometer Figure Information of third parties may be subject to additional restrictions. For optimum accuracy, a one point calibration is recommended. Glue or cement the device to a surface and the temperature should be within about 0. The influence of these currents on the minimum and maximum reverse dafasheet flowing through the LM should be calculated and be maintained in the range of 0.

Calibrated Error Figure 3. Compensates for both sensor and resistor tolerances 1. Wide Operating Supply Figure TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

Additional error can be introduced by varying load currents or varying supply voltage. Dynamic Impedance Figure 6. No license is granted by implication or otherwise under any patent or patent rights of STMicroelectronics. Page numbers for previous revisions may differ from page numbers in the current datasheer.

Product device recommended for new designs. Calibrated Error at Extended Temperature.

LM135-150-36P

Accuracy measurements are made in a well-stirred oil bath. A pot connected across the LM 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.

For other conditions, self heating must be considered. 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. This glossary lists and explains terms, acronyms, and definitions.

Catasheet in output voltage versus temperature are only slope or scale factor errors datashfet a slope calibration at one temperature corrects at all temperatures. The circuit has a dynamic impedance of less than. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
