Why not get an Op-amp Data book and do a bit of reading, 26 posts of if "If anyone knows then tell me".
You want everyone else to do your homework. You ask for help and then abandon the post in seehttp://www.sonsivri.com/forum/index.php?topic=25952.msg87952#msg87952
And then start a new "I want post"
sorry if you think this hard but you are on a warning and a mute. (both have not worked in the past)
