IC - LM35 Temperature Sensor schematic with Explanation and Characteristics

LM 35 temperature sensor IC is an IC chip semiconductor production Natioanal used to determine the temperature of an object or space as an electric stove, or can also be defined as an electronic component that is used to change the temperature changes are acceptable for changes in bulk electrical. LM35 temperature sensor IC temperature change can change a change in the output voltage. The LM35 temperature sensor IC required voltage 5 volt DC source and DC Current consumption 60 mA in operation. Temperature sensor LM 35 Fitness is an IC chip with containers ranging in temperature sensor LM35 TO-92 overall package is packaged as shown in the following figure.

From the picture above it can be seen that the temperature sensor IC LM35 basically have 3 pin that serves as a source of supply voltage of +5 volts DC, as a result of sensing the output pin in the form of a change in the DC voltage and Vout pin to Ground.

Some of the IC - LM35 temperature sensor characteristics are:

Temperature sensitivity, with linear scaling factor between voltage and temperature 10 mVolt / º C, so it can be calibrated directly in centigrade.
Have the accuracy or the accuracy of the calibration is 0.5 º C at 25 º C.
Has a maximum operating temperature range between -55 º C to +150 º C. Working at a voltage of 4 to 30 volts.
Has current low at less than 60 mA.
Have a low self-heating (low-heating) of less than 0.1 º C in still air.
Has a low output impedance is 0.1 W for 1 mA load.
have Nonlinearities only about ± ¼ º C.
