Hello All,
I am trying to get a copy of a application note by Hitachi for a MOSFET amp published in 1989. You probably have seen amps designed with the note's influence - the voltage gain stage is a long tailed pair (differential amp) driven from the input LTP. Just about all the recent AUS. magazine designs have used it.
Anyway, can anyone help with a link or a copy of this note? I have "googled" but all I can find is some sod who wants 12 Euro for someone else's work.
All help appreciated
