Rather than using a fixed gain INA, use a gain and offset DIff Amp OA design to scale your input to the desired output.
if 0 to 2V in and 0 to 3.3V out then non-inverting gain = 1.65
If -2V to +2V in and 0 to 3.3V out then gain = 0.825 and offset = +1.65V (=Vss/2)
I suspect you want to measure high current AC primary so you want to measure both polarities > +/- x.xx V so you compute dual thresholds y using Vdd/2 as a null reference.
But keep in mind radiated CM noise. Having 120 dB CM conducted noise rejection is wasted if the cable is only 50dB CMRR with a 500A impulse going thru a Rogowski coil, so choose your cable wisely. that is already 50dB above your current sensor secondary. Getting 100 dB attenuation of Injected H field current impulse near the cable may depend on doubled shielded twisted pair with a Pi filter CM Choke and orthogonal orientation. This is what I have had to use in the past with monitoring 10kA arc welders.
opinions and design specs?
For the OCP logic output, I would ask if real-time and polarity is important. Because, knowing the high Remanence Currents from saturation on power up due to the phase difference and resulting magnetization V difference between power input stop and restart, start current can be quite large if starting 180 phase shifted and make some Xfmr's "hum" for a long time until unsaturated or return to zero averarge magnetization current. Also Arcs can be polar so a single-sided OCP logic output does not use all the useful information available on different faults.
