Clay,
I would really like to have a copy of your test board for this effort.
I'm sure it will be a challenging layout. But it could be a very handy
piece of hardware. Supporting a PCA order would easy to do.

I always buy more than one PCB, 5 - 6 don't cost any more than 1.
Unfortunately, I don't think my favorite prototype shop (PCB123) will be
suitable for a layout with voids in the ground plane (reduce parasitic C) under
the opamp and R4003C on the top layer, so I will have to do a 'real' PCB. I
was also planning on using the leadless version of the part, which could be
challenging for home assembly.
Everything is leadless these days. Gives me fits sometimes. I just went
through a nightmarish experience with a leadless ARM7 processor that needed
some wires added. I replaced it with a leaded part at a cost of 2 mm PCB area
. . . but I digress.
