Description

The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional 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 andplusmn;andfrac14;anddeg;C at room temperature and andplusmn;andfrac34;anddeg;C over a full andminus;55anddeg;C to 150anddeg;C 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 andmu;A from the supply, it has very low self-heating of less than 0.1anddeg;C in still air. The LM35 device is rated to operate over a andminus;55anddeg;C to 150anddeg;C temperature range, while the LM35C device is rated for a andminus;40anddeg;C to 110anddeg;C range (andminus;10anddeg; 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.
