1 / 12 page TLH5516 December 1994 LM35LM35ALM35CLM35CALM35D Precision Centigrade Temperature Sensors General Description The LM35 series are precision integrated-circuit tempera- ture sensors whose output voltage is linearly proportional to the Celsius (Centigrade) temperature The LM35 thus has an advantage over linear temperature sensors calibrated in Kelvin as the user is not required to subtract a large con- stant voltage from its output to obtain convenient Centi- grade scaling The LM35 does not require any external cali- bration or trimming to provide typical accuracies of g C at room temperature and g C over a full b55 to a150 C temperature range Low cost is assured by trimming and calibration at the wafer level The LM35’s low output imped- ance linear output and precise inherent calibration make interfacing to readout or control circuitry especially easy It can be used with single power supplies or with plus and minus supplies As it draws only 60 mA from its supply it has very low self-heating less than 01 C in still air The LM35 is rated to operate over a b55 to a150 C temperature range while the LM35C is rated for a b40 to a110 C range (b10 with improved accuracy) The LM35 series is available packaged in hermetic TO-46 transistor packages while the LM35C LM35CA and LM35D are also available in the plastic TO-92 transistor package The LM35D is also available in an 8-lead surface mount small outline package and a plastic TO-202 package Features Y Calibrated directly in Celsius (Centigrade) Y Linear a 100 mV C scale factor Y 05 C accuracy guaranteeable (at a25 C) Y Rated for full b55 to a150 C range Y Suitable for remote applications Y Low cost due to wafer-level trimming Y Operates from 4 to 30 volts Y Less than 60 mA current drain Y Low self-heating 008 C in still air Y Nonlinearity only g C typical Y Low impedance output 01 X for 1 mA load Connection Diagrams TO-46 Metal Can Package TLH5516 – 1 Case is connected to negative pin (GND) Order Number LM35H LM35AH LM35CH LM35CAH or LM35DH See NS Package Number H03H TO-92 Plastic Package TLH5516 – 2 Order Number LM35CZ LM35CAZ or LM35DZ See NS Package Number Z03A SO-8 Small Outline Molded Package TLH5516 – 21 Top View NC e No Connection Order Number LM35DM See NS Package Number M08A TO-202 Plastic Package TLH5516 – 24 Order Number LM35DP See NS Package Number P03A Typical Applications TLH5516 – 3 FIGURE 1 Basic Centigrade Temperature Sensor (a2 Cto a150 C) TLH5516 – 4 Choose R1 ebVS 50 mA VOUTea1500 mV at a150 C ea 250 mV at a25 C eb 550 mV at b55 C FIGURE 2 Full-Range Centigrade Temperature Sensor TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation RRD-B30M75Printed in U S A |
