Hi Wakaka,

i Dont want to use LM35 because i will need A/D conversor.
If i use LM70 , a can conect without conversor A/D because i have digital output in this component.

That should give you some ideas. You may want to consider the I2C part mentioned in a couple of the posts. That may prevent you from having to write your own driver....

Good luck,
