Precision Centigrade Temperature Sensor

The LM35 series are precision integrated-circuit Temperature 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 constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of C at room temperature and C over a full -55 to +150C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35 's low output impedance, 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 ?A from its supply, it has very low self-heating, less than 0.1C in still air. The LM35 is rated to operate over a -55 to +150C temperature range, while the LM35C is rated for a -40 to +110C range (-10 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-220 package.
