Not always, but sometimes.  If you can find an SOIC datasheet with the pa=
ckage=20
dimensions and PCB layout, then use that as a guide and adjust accordingl=
y=20
for the Cerpak with the diff dimensions.  You'll have a decent idea of ho=
w mu=20
pad you need around each pin, especially since the pin pitch is the same =
on=20
both packages (0.050" IIRC).

If not, use the SOIC pad layout for some other part in Eagle and the data=
sheet=20
for that part as a starting point, and then adjust accordingly for the=20
Cerpak.

Alternatively, have you asked AD's tech support.  I'm sure they'd have th=
is=20
layout spec for boards they've built and let you have it.

Cheers,
-Neil.
