The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of 1/4C at room temperature and 3/4C over a full -55C to 150C temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low-output impedance, linear output, and precise inherent calibration of the LM35 device makes interfacing to readout or control circuitry especially easy. The device is used with single power supplies, or with plus and minus supplies. As the LM35 device draws only 60 A from the supply, it has very low self-heating of less than 0.1C in still air. The LM35 device is rated to operate over a -55C to 150C temperature range, while the LM35C device is rated for a -40C to 110C range (-10 with improved accuracy). The LM35-series devices are available packaged in hermetic TO transistor packages, while the LM35C, LM35CA, and LM35D devices are available in the plastic TO-92 transistor package. The LM35D device is available in an 8-lead surface-mount small-outline package and a plastic TO-220 package. 1 Calibrated Directly in Celsius (Centigrade) Linear + 10-mV/C Scale Factor 0.5C Ensured Accuracy (at 25C) Rated for Full -55C to 150C Range Suitable for Remote Applications Low-Cost Due to Wafer-Level Trimming Operates From 4 V to 30 V Less Than 60-A Current Drain Low Self-Heating, 0.08C in Still Air Non-Linearity Only 1/4C Typical Low-Impedance Output, 0.1 for 1-mA Load 2 Applications * * * * Power Supplies Battery Management HVAC Appliances Device Information(1) PART NUMBER LM35 PACKAGE BODY SIZE (NOM) TO-CAN (3) 4.699 mm x 4.699 mm TO-92 (3) 4.30 mm x 4.30 mm SOIC (8) 4.90 mm x 3.91 mm TO-220 (3) 14.986 mm x 10.16 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.

The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of 1/4 C at room temperature and 3/4 C over a full -55C to 150C temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low output impedance, linear output, and precise inherent calibration of the LM35 device makes interfacing to readout or control circuitry especially easy. The device is used with single power supplies, or with plus and minus supplies. As the LM35 device draws only 60 A from the supply, it has very low self-heating of less than 0.1C in still air. The LM35 device is rated to operate over a -55C to 150C temperature range, while the LM35C device is rated for a -40C to 110C range (-10 with improved accuracy). The temperature-sensing element is comprised of a delta-V BE architecture. The temperature-sensing element is then buffered by an amplifier and provided to the VOUT pin. The amplifier has a simple class A output stage with typical 0.5- output impedance as shown in the Functional Block Diagram. Therefore the LM35 can only source current and it's sinking capability is limited to 1 A. 7.2 Functional Block Diagram A1 1.38 VPTAT +VS nR1 Q1 Q2 10E + A2 E VOUT = 10 mV/C V0 .125 R2 nR1 8.8 mV/C i R2 7.3 Feature Description 7.3.1 LM35 Transfer Function The accuracy specifications of the LM35 are given with respect to a simple linear transfer function: VOUT = 10 mv/C x T where * * VOUT is the LM35 output voltage T is the temperature in C (1) 7.4 Device Functional Modes The only functional mode of the LM35 is that it has an analog output directly proportional to temperature.

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 The features of the LM35 make it suitable for many general temperature sensing applications. Multiple package options expand on it's flexibility. 8.1.1 Capacitive Drive Capability Like most micropower circuits, the LM35 device has a limited ability to drive heavy capacitive loads. Alone, the LM35 device is able to drive 50 pF without special precautions. If heavier loads are anticipated, isolating or decoupling the load with a resistor is easy (see Figure 12). The tolerance of capacitance can be improved with a series R-C damper from output to ground (see Figure 13). When the LM35 device is applied with a 200- load resistor as shown in Figure 16, Figure 17, or Figure 19, the device is relatively immune to wiring capacitance because the capacitance forms a bypass from ground to input and not on the output. However, as with any linear circuit connected to wires in a hostile environment, performance is affected adversely by intense electromagnetic sources (such as relays, radio transmitters, motors with arcing brushes, and SCR transients), because the wiring acts as a receiving antenna and the internal junctions act as rectifiers. For best results in such cases, a bypass capacitor from VIN to ground and a series R-C damper, such as 75 in series with 0.2 or 1 F from output to ground, are often useful. Examples are shown in Figure 13, Figure 24, and Figure 25. HEAVY CAPACITIVE LOAD, WIRING, ETC. + 2k LM35 TO A HIGH-IMPEDANCE LOAD OUT v Figure 12.

In noisy environments, TI recommends adding a 0.1 F from V+ to GND to bypass the power supply voltage. Larger capacitances maybe required and are dependent on the power-supply noise. 10 Layout 10.1 Layout Guidelines The LM35 is easily applied in the same way as other integrated-circuit temperature sensors. Glue or cement the device to a surface and the temperature should be within about 0.01C of the surface temperature. The 0.01C proximity presumes that the ambient air temperature is almost the same as the surface temperature. If the air temperature were much higher or lower than the surface temperature, the actual temperature of the LM35 die would be at an intermediate temperature between the surface temperature and the air temperature; this is especially true for the TO-92 plastic package. The copper leads in the TO-92 package are the principal thermal path to carry heat into the device, so its temperature might be closer to the air temperature than to the surface temperature. Ensure that the wiring leaving the LM35 device is held at the same temperature as the surface of interest to minimize the temperature problem. The easiest fix is to cover up these wires with a bead of epoxy. The epoxy bead will ensure that the leads and wires are all at the same temperature as the surface, and that the temperature of the LM35 die is not affected by the air temperature. The TO-46 metal package can also be soldered to a metal surface or pipe without damage. Of course, in that case the V- terminal of the circuit will be grounded to that metal. Alternatively, mount the LM35 inside a sealedend metal tube, and then dip into a bath or screw into a threaded hole in a tank. As with any IC, the LM35 device and accompanying wiring and circuits must be kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold temperatures where condensation can occur. Printed-circuit coatings and varnishes such as a conformal coating and epoxy paints or dips are often used to insure that moisture cannot corrode the LM35 device or its connections. These devices are sometimes soldered to a small light-weight heat fin to decrease the thermal time constant and speed up the response in slowly-moving air. On the other hand, a small thermal mass may be added to the sensor, to give the steadiest reading despite small deviations in the air temperature. Table 2.
