The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ˚ Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centi- grade scaling.
This document provides a comprehensive description of the LM35 precision centigrade temperature sensor, including its linear output, low self‑heating, and wide operating temperature range. It lists the available packages (TO‑46, TO‑92, SO‑8, TO‑220) and their ordering numbers.
Electrical characteristics such as accuracy, sensor gain, supply voltage range, and quiescent current are presented, followed by typical performance graphs, application examples, and mechanical dimensions. A life‑support policy disclaimer concludes the handbook.
