Product Description
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 temperature centigrade scaling.
Sensor types: LM35A/ LM35CA/ LM35/ LM35C/ LM35D
| Typical Applications | Features |
| • HVAC | • Calibrated directly in °Celsius (centigrade) |
| • Refrigerator | • Linear ±10.0 mV/ºC scale factor. |
| • Ice house | • 0.5ºC accuracy guarantee able (at 25ºC) |
| • Library | • Low cost due to wafer-level trimming. |
| • Portable equipment | • Less than 60 μA current drain. |
| • Industrial equipment | • Low self-heating, 0.08ºC in still air. |
| • Non-linearity only ±1/4 ºC typical. | |
| • Low impedance output, 0.1 W for 1 mA load. |
