#149944 - Does that mean... Responding to: ???'s previous message |
that pin VAREF may stay unconnected while the ADC supply voltage is 3 V? Does this setup define a voltage range for ADCIN between 0 and 3 V?

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 | |

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