The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.

Features:

• Calibrated directly in ˚ Celsius (Centigrade)
• Linear + 10.0 mV/˚C scale factor
• 0.5˚C accuracy guaranteeable (at +25˚C)
• Rated for full −55˚ to +150˚C range
• Suitable for remote 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
