Hi, Jared,
Cool! (pun not really intended)
How hot is the IC getting?
The OPA1632 was the best IC to be mated to this device when it was released. Unfortunately, I don't follow the op amps that our op amp group releases (as you can imagine, we have many groups at TI).
You might try posting a post in the op amp e2e asking about the op amp.
