AVR-Chat

hello guys,

i used a digital temp sensor to monitor a temperature of a certain ic 
near to it. Now my question is that what part of the IC sense the 
temperature? Is it their body? or a certain PIN?

thanks,

mago

Body.

Usually, this is not a problem because temperature
gradients are low in most situations. In this case pin
temperature is not very different from body. Also, most
temperature sensors are only accurate to about 2C with a
few to 0.5C.

  It is a sensor built into the silicon on the actual chip die.  So
basically, pretty much the center of the chip.

you made sense.. no significant defference between the body and the pin temperature.
   
  thank you

You could use a thermistor in series with a capacitor.
See how long it takes to charge up to see what the resistance is.
This is a cheap solution I have used successfully many times.
