I'm trying to simulate the behavior of TI's OPA2674ID on LTSpice, here's the link to the datasheet for your convenience:

The following circuit diagram shown below is given in the datasheet and I have modeled my simulation's schematic after it.

Here's a cropped version of my simulation's schematic:

RL, VS, and RF were chosen based on the information below:

RG was obtained from the formula given in the first attached image while CG was calculated using the cutoff frequency formula (f = 1/(2*pi*CG*RG).

According to the datasheet, I should be obtaining a differential gain of +9 but when I ran my simulation and checked for the voltages across RLoad and across the non-inverting input, the voltage output is lesser than 5V. Shouldn't the output voltage be scaled up instead of down? How would I scale up the voltage and the current as well to obtain a power of about 17W across the load resistor? The source voltage is meant to represent the AD9834 chip by the way.

Here's a snip of the simulation's results:

I'd appreciate any help and criticism I could get regarding my question. Thank you in advance!
