SSM2038 help again :)

[Yoshiki Ohmura (Yoshi)]

OK I got Barry's Datasheet book, and after comparing the 2033 and 2038 I
noticed that they are pretty similar.  So I basicaly based the design for
my 2038 circuit on Berry's 2033 design from his EMC book.  However the
inputs on the two chips are different, the 2038 has Expo + and Expo -
where  the 2033 only has expo.  I'm not quite sure how to buffer the
input, and where the out of the op amp should go and how it should go
there.  If somebody who is familiar with the 2033 and has the datasheet
for the 2038, could have a look and give me a suggestion I would be very
happy :) 

Thanks
