Ah. Ye old edit. I always miss them.
>> EDIT: ADG201A isn't an assignment, it's a part. What are you doing with the analog switch?
I'm not sure I know what you mean ... We have to design the switch and the control part of it. Just one mind, I don't know if I could handle four the that are in the schematic I linked to
So, from the image on the page I linked to the section:
IN1, D1 and S1.
We don't have to design how it would rest on a chip or anything. Just the widths, lengths, etc. That what you were asking?
