Description
LM35 Precision Centigrade Temperature Sensors November 2000 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 Calibrated directly in ˚ Celsius (Centigrade) n Linear + 10.0 mV/˚C scale factor n 0.5˚C accuracy guaranteeable (at +25˚C) n Rated for full
Applications
* n Low cost due to wafer-level trimming n Operates from 4 to 30 volts n Less than 60 µA current drain n Low self-heating, 0.08˚C in still air n Nonlinearity only ±1⁄4˚C typical n Low impedance output, 0.1 Ω for 1 mA load
Typical Applications
