Hi,

I'm a student working on a project with the LPC4370. My current goal is to make the HSADC work precise, for measuring with a accuracy of 1mV. As it seems that I can't reach this goal, I was wondering if someone else has cracked this mark. If yes, I'd like to now following points:

- was it hard to get there?
- at witch samplerate does the HSADC work?
- are there more channels used or only one?
- do you use one ground plane for analog and digital signals, or are they separated?

looking forward for answers

greetings
baum
