#149900 - VAVCC usable as ADC reference voltage? Responding to: ???'s previous message |
VAVCC is the supply voltage for the ADC. I guess, it is only for supply and can not be used as a replacement for VAREF to define the ADC voltage range. Am I right?

| 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 | |

no,yes | 01/01/70 00:00 |
