The low impedance and linear output make interfacing to readout or control circuitry especially easy. The LM135 operates over a -55C to 150C temperature range while the LM235 operates over a -40C to 125C temperature range. The LM335 operates from -40C to 100C. 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- dynamic impedance, the device operates over a current range of 400 A to 5 mA with virtually no change in performance. When calibrated at 25C, the LM135 has typically less than 1C error over a 100C 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 (-273.15C). 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: where 8 Submit Documentation Feedback Copyright (c) 1999-2015, Texas Instruments Incorporated Product Folder Links: LM135 LM135A LM235 LM235A LM335 LM335A LM135, LM135A, LM235, LM235A, LM335, LM335A www.ti.com SNIS160E - MAY 1999 - REVISED FEBRUARY 2015 Feature Description (continued) * * T is the unknown temperature in degrees Kelvin To is a reference temperature in degrees Kelvin (1) By calibrating the output to read correctly at one temperature the output at all temperatures is correct.

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 Typical Application Figure 13. Basic Temperature Sensor 8.2.1 Design Requirements Table 1. Design Parameters PARAMETER Accuracy at 25C Accuracy from -55 C to 150 C Forward Current Temperature Slope EXAMPLE VALUE 1C 2.7C 1 mA 10m V/K 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. 10 Submit Documentation Feedback Copyright (c) 1999-2015, Texas Instruments Incorporated Product Folder Links: LM135 LM135A LM235 LM235A LM335 LM335A LM135, LM135A, LM235, LM235A, LM335, LM335A www.ti.com SNIS160E - MAY 1999 - REVISED FEBRUARY 2015 8.2.3 Application Curve Figure 14.

Glue or cement the device to a surface and the temperature should be within about 0.01C 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. 10.2 Layout Example VIA to ground plane VIA to power plane ADJ - N.C.

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 1C error. Figure 34. Cable Connected Temperature Sensor Table 2.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width.
