SNIS159E AUGUST 1999 REVISED JANUARY 2015 LM35 Precision Centigrade Temperature Sensors
1 Features 1 3 Description
The LM35 series are precision integrated-circuit temperature devices with an output voltage linearlyproportional to the Centigrade temperature. 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 C at room temperature and 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). Th...
