LM35DZ Temperature Sensor
- The LM35 datasheet specifies that this ICs are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.
- Calibrated directly in o Celsius (Centigrade)
- Linear + 10.0 mV/oC scale factor
- 0.5oC accuracy guaranteeable (at +25oC)
- Rated for full −55o to +150oC 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, 0.08oC in still air
- Nonlinearity only ±1⁄4oC typical
