AD7192 Pseudo Differential Connection

Hi!

I am using the AD7192 with 4 pseudo differential inputs, but i can only find examples and evaluation stuff for differential inputs.

I want to know if i should use R-C Combinations on the inputs (like 100 Ohm in series and 0.1uF to Analog Ground) or don't when using unbuffered mode.

AIN 1 - 100 Ohm - Analog Voltage

                           0.1uF

                            |

                       Analog GnD

AINCOM should also be Analog Ground in the pseudo differential case, when measuring between ADVV and AGND correct?
