AD7124-4 Pseudodifferential

Good day,

I use from a Pseudodifferential opamp architecture at the inputs of ADC. It means that the inputs comming from the Sensor will be amplifier at gain=50 and shifted by 1.5V and finally goes to AIN_P.

On the other hand, 1.5V also is connected to AIN_N.

My Question: is it possible to remove the final amplifier stage and instead, use from the internal PGA of AD7124?

I already did this for differential configuration but for the Pseudodifferential I have no idea how to shift the level by 1.5V for internal PGA.

Thank you for your time and considerations.
