i guess problem is how to minimize
hardware for some ratiometric sensor or potentiometer. I didnt worked with this part , but from datasheet it seems whole circuit can be powered by 3V. ADC is only 10 bit, so any VCC noise will be non-significant for measurement, i think. |

| No, unless you mean VAVCC | 01/01/70 00:00 | |
| VAVCC usable as ADC reference voltage? | 01/01/70 00:00 | |
| Datasheet says that you can | 01/01/70 00:00 | |
| 'can" "should' and 'good' are 3 different words | 01/01/70 00:00 | |
| varef is specified 2,4...3V range | 01/01/70 00:00 | |
| but not if you want any precision | 01/01/70 00:00 | |
| why not | 01/01/70 00:00 | |
| Well, I have yet to see any VCC that ... | 01/01/70 00:00 | |
| Does that mean... | 01/01/70 00:00 | |
no,yes | 01/01/70 00:00 |
