For AD7356 ADC i’m using AD8138 differential OpAmp (by referring the AD7356 evaluation board schematics and ad7356 datasheet).

I made a pcb to check the ADC, when i measure the output pin of AD8138, it shows +4V and -4V at OUT+ & OUT- pins.

The input is connected to ground and irrespective of voltage at VOCM pin the output is +/-4V.

Please see the the attached schematics.

please suggest me solution for the above issue
