Description
LM35 Precision Centigrade Temperature Sensors July 1999 LM35 Precision Centigrade Temperature Sensors General .
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temper.
Features
* n n n n n n n n n n n Calibrated directly in ˚ Celsius (Centigrade) Linear + 10.0 mV/˚C scale factor 0.5˚C accuracy guaranteeable (at +25˚C) Rated for full
Applications
* Low cost due to wafer-level trimming Operates from 4 to 30 volts Less than 60 µA current drain Low self-heating, 0.08˚C in still air Nonlinearity only ± 1⁄4˚C typical Low impedance output, 0.1 Ω for 1 mA load
