ADC, pref and dynamic range

[HenrikOlsson]

Bloody h..l, why can't I edit my own posts here, it's not even been 20 minutes since I posted. It's starting to getting on my nerves.

On topic: I just realised I linked to the 16LF1824 datasheet and not the 12LF1824, so make sure you verify the numbers with the correct datasheet.

EDIT: So, editing is alowed, for 10 seconds or whatever... And I just realised that you ARE using the 16LF1824 but I mistakingly wrote 12LF and then got confused when the link opened the 16LF part datasheet.

It's early in the morning, I need my coffee. Sorry about this!

Hi Bert/Henrik (Henrik no worries...I have mornings like that)

As they say....RTFDS!

I have to say I'm puzzled here.. a day or two ago, while dabbling, I'm pretty sure I set the ADC pref to internal FVREF...and then set the FVREF to 1.024V - it worked?! (so I guess the answer is the lowest I can take VREF is 1.024V....but I'm not meant to! Therefore to get a better 'official range' would be option 2 above....use a lower VCC.....1.8V)

Many thanks
