AD633 specs

[List, Christopher]

The chip is set up so that you can set the "divide-down" of the output. With
a pair of resistors I believe. For a +/-5v input, you'd set it up to use a
1/5 "division factor", so the "real" math of the chip would be:  (A * B) / 5
Works as advertised. Great chip. I recommend the trimmers, but you could try
leaving room for them and leaving them out on the first pass. It'll
definitely work without them, but they help with the bleed-through.
