Well thank you for all your suggestions I still have have very little luck. I called linear and someone is suppose to be assisting me in find a solution. I've sent them my orcad files so hopefully they will be able to find something. I'll make sure to post to the list what I find. Thanks all, Aaron -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
