You can use the lm35dz sensor in temperature measurement applications. Thanks to its small size, you can make more precise measurements by placing it in the area you want to measure the temperature.
Features:
Calibrated directly in Degree Celsius (Centigrade)
Linear at 10.0 mV/°C scale factor
0.5°C accuracy guarantee-able (at a25°C)
Suitable for remote applications
Low cost due to wafer-level trimming
Operates from 4 to 30 volts
Less than 60 mA current drain
Low self-heating, 0.08°C in still air
Non-linearity only 0.25°C typical
Low impedance output, 0.1Ωfor 1 mA load
Scope of application:
power supplies
battery management systems
motor driver protection circuit
Package Included:
