TLV9062: Variable gain is observed on output while amplifying the differential signal from CT

Part Number: TLV9062

Hello Ti E2E

I am working on a design, where I am measuring an AC current using a CT with a 1:1000 Ratio and using TLV9062 to amplify the CT output with a gain of ~50. I need to measure the whole signal from CT output.

So I have pulled up the non-inverting input to 3.3V, As I am powering the OP-Amp with a single supply +5V. I need to measure both half-cycles, so the input differential signal will offset to 3.3V. Similarly on the output side the amplified signal will be offset to 3.3V

During simulation, behavior is as per expected but when checking on the actual circuit, behavior is not expected, and doing the back calculations finds the gain of the circuit is varying with respect to the input signal.

Attaching the sch for your reference.

I am requirement is as mentioned above. Kindly let us know your feedback on this behavior.

Thanks & Regards
