Another PIC Parameter

I spoke with Prof. Brixen today about the best way to interface the LM34 temperature sensor with a PIC microcontroller. I've wanted to keep the PIC used to be as simple as possible. (I must admit I do wish the smaller 8-pin versions had the I²C hardware interface, but that's asking alot).

I going to need to use a PIC that has at least one 8-bit ADC. I'm trying to avoid using a op-amp to increase the 10mV/^oC to a wider voltage range to use the full 8-bit range. I need to study the PIC families and see if any allow you to change the reference voltage of the ADC. (Update: Several of the PIC MPUs allow you to use either V_DD or another reference voltage for the ADC. This may require an additional chip to provide precision voltage reference.)

Off to look at a lot of datasheets...
