Test circuit temperature before construct to pic controller.As a result of continued IC process scaling, the importance of leakage power consumption is increasing. Leakage accounts for 40% of the power consumption of today’s high-performance microprocessors. Power consumption, temperature, and performance must now be optimized during the entire design flow. Leakage power
consumption and temperature influence each other: increasing temperature increases leakage and vice versa . Leakage power estimation is frequently used in IC synthesis, within which it may be invoked tens of thousands of times: it must be both accurate and fast.

- It has an output voltage that is proportional to the Celsius temperature.
- The scale factor is .01V/oC
- The LM35 does not require any external calibration or trimming and maintains an accuracy of +/-0.4 oC at room temperature and +/- 0.8 oC over a range of 0 oC to +100 oC.
- Another important characteristic of the LM35DZ is that it draws only 60 micro amps from its supply and possesses a low self-heating capability. The sensor self-heating causes less than 0.1 oC temperature rise in still air.
- TO-92 plastic transistor-like package,
- T0-46 metal can transistor-like package
- 8-lead surface mount SO-8 small outline package
- TO-202 package. (Shown in the picture above)
