Idiot question about voltage divider

[forgotthelot]

Returning to this subject after years and years away so sorry for the ridiculous question...I have a resistive touch screen (220-550 ohms) - I need it to supply me ADC with (as near as possible) 0-5V and sink as little current as possible...can someone point me in the right direction?

Humble apologies for my stupidity...

I don't know if I should thank you or cry - I should have known it was never going to be that simple. Still...Ti are sending free samples by fedex so my project shouldn't be dealyed too much.

Thanks for your time - much appreciated, honestly
