Other Parts Discussed in Thread: THS3202, TINA-TI

I'm using Altium in order to simulate this simple G = 2 non-inverting amplifier (the same that can be found in TSH3202EVM):
The output of the circuit above is this:
As can be seen, the output has 1 mVpp when the input is 60mVpp. This makes no sense. I'm using this simulation file:
