The datasheet shows that the output cannot go higher than about 17V in your circuit.


Top? Bottom? Pin 4 is for the positive supply (Vcc) and pin 11 is for the negative supply (Vss).

Your circuit does not work because it has no input coupling capacitor and your DC-connected signal generator has its ground at the opamp's negative supply. Then the opamp inverts the negative DC causing the output to go as positive as it can.
The negative supply IS NOT GROUND! The negative supply is ground when an input coupling capacitor is used.
