Buyers are responsible for their products and applications using TI components. Dynamic Impedance Figure 6. The output of the device calibrated or uncalibrated can be expressed as: Datashwet Temperature Sensor Figure STMicroelectronics products are not authorized for use as critical components in life support devices or.

The low impedance and linear output make interfacing to readout or control circuitry especially easy. Select R3 and R4 for thermocouple type 2.

National Semiconductor – datasheet pdf

Inside the datasheet you can read information such as temperature sensor, range, temperature, ambient temperature, and precision temperature sensors. For browser-based versions of this data sheet, refer to the left-hand navigation. Optocouplers – Texas Instruments. Simple Temperature Control Adjust for 2. The Operating Output Voltage Change with Current specification can be used to calculate the additional error which could be up to 1 K l,135 from the LMA, for example.


Leave a Reply Cancel reply Your email address will not be published. If the sensor is used in an ambient where the thermal resistance is constant, self-heating errors can be calibrated out.

Compensates for both sensor and resistor tolerances 1. Even more, this datasheet contains discussion regarding temperature sensors, errors, impedance, and calibration. No license is granted by implication or otherwise under any patent or patent rights of STMicroelectronics.


Additional error can be introduced by varying load currents or varying supply voltage. Documents Flashcards Grammar checker. The datasheet contains discussion related to temperature range, accuracy, temperature error, and sensor. Page numbers for previous revisions may differ from page numbers in the current version. A to 5mA without alteration of its characteris. TI is not responsible or liable for any such statements. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Adjust R1 for the voltage across R3 equal to the Seebeck Coefficient times ambient temperature in degrees Kelvin. pm135


Pin Configuration and Functions Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. The temperature sensed by the TO92 package could greatly depend on velocity of the airflow as well. The single point calibration works because the.


The circuit output calibrated or not can be given. JavaScript is required to post comments.

The datasheet contains information such as range, typical performance characteristics, centigrade temperature sensors, accuracy, and characte 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 lm15. 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.

Important Information and Disclaimer: To insure that the temperature of the LM die daasheet not affected by the air temperature, mechanically connect the LM leads with a bead of epoxy to the surface being measured.

Adjust R2 for voltage across R4 corresponding to thermocouple. This publication supersedes and replaces all information. Response Time Figure 5.
