Xmega ADC calibration value
Lots of them! The reference voltage cannot be 3.3V, in the xmega32a4 it must be around 2V. The linearity is a kind of a joke. In unsigned mode, single-ended, you must connect a...

Xmega ADC problems & "solutions"
I have read some posts, and got some info from Atmel, saying that the ADC behaves a lot better in signed differential mode than in unsigned single ended. I use unsigned single...

Is xmega series reliable for mass production?
We are havinga lot of problems due to the ADc limitations of the Rev.A silicon of the ATXmega32A4. Has anyone tested the ADC of Silicon Rev.B???

From Mega to XMega
We are facing a lot of restrictions with the ADC's of the ATXmega32A4. Atmel told us that in th new silicon (Rev.B) most of these issues were going to be solved. Is there anyone...

xmega adc calibration (factory signature row)
I also read 0x444 from all samples.
