SAM4E ENOB of ADC

Mon Sep 21, 2015 11:29 pm

I have reviewed the datasheet for the ATSAM4E16E and it's 16-bit ADC. I am not an expert in this field, but I am wondering what the ENOB for the ADC on these parts is. Is it truly 16bit? I have been told by other mcu specialists that the Effective Number of Bits (ENOB) when using a 16 bit ADc can actually be closer to 14.
Is there anywhere I can find this data for the SAM4E?

Thanks

SAM4E does not have a 16-bit ADC at all - see the notes on page 4. The ENOB is 9 in worst case conditions.
