ic to range ADC inputs
following this tutorial form analog devices I came up with the following that seems like it will work. I had to change the op-amp to the AD8226.

I only need to compare the error between using the internal gain of the ADC's instrumentation amplifiers and using the AD8226. I plan on using a solid state relay like the TLP3409S or TLP175A.
