Yes.  I did this recently with an LM35DT ... it's stable, seems to be qui=
te=20
accurate (I "calibrated" it), and so far there are no flames or smoke. :-=
)

Now I know you didn't ask this part, but at 10mV/deg C the output voltage=
=20
range of the LM35DT is less than ideal, so I'm using a 2.5V reference int=
o=20
the PIC to get more range out of the A/D.

Cheers,
-Neil.
