#149885 - Atmel T89C51CC02: ADC reference voltage |
Hi! Is the Atmel T89C51CC02 able to use its supply voltage as the ADC reference voltage? I know, that there are microcontrollers that have a switch for selecting external and internal reference voltage, but I cant find a hint in the Atmel data sheet. Anyone does it know for sure? Thanks. |

| 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 |
