Can't find a spec, looking at the LPC12XX family parts, anyone know or can point me in the right direction?

Thanks

I see it's 3 years later and no answer. Now I need to know this for a project. Are there ANY specifications for the analog comparators on LPC parts? Offset voltage? Propagation delay? Anything?

For lower speed work, I can verify the comparator works fine, but now I need a higher speed function.

Hi jdurand,
Which LPC device do you want to use? LPC1500 is one of the microcontroller which has high speed analog comparator in it
see specifications at page 82 of the datasheet.

Great, thanks! Could you possibly stick that chart in the LPC122x data sheets? I'm using the LPC1226 for this project, but use many different versions in different products. For example, I'll be using an LPC8xx in an iAccessory (love that switch matrix).
