[missing_dave]

hey all...this seemed like the best place to post this..(admin feel free to repost if not)

anybody know what these op amps are all about?? i know they share the same "4558" as the more common ts type...but the  "ana" before the 4558?? are these some holy grail 45588 or is it just wishful thinking that i have something cool??

i suggest you try reposting in the "building your own stompbox" forum.  this post may get lost here.

and i haven't a clue about your ana4558.  sorry, paul
