When a conversion takes place, the common mode is rejected,
resulting in a noise-free signal of amplitude 2 × (4 × VREF)
to +2 × (4 × VREF) corresponding to Digital Code 4096 to
Digital Code +4095.

Pseudo Differential Inputs
The AD7323 can have two pseudo differential pairs or three
pseudo differential inputs referenced to a common VIN input.
The VIN+ inputs are coupled to the signal source and must have
an amplitude within the selected range for that channel as
programmed in the range register. A dc input is applied to the
VIN input. The voltage applied to this input provides an offset
for the VIN+ input from ground or a pseudo ground. Pseudo
differential inputs separate the analog input signal ground from
the ADC ground, allowing cancellation of dc common-mode
voltages.
When a conversion takes place, the pseudo ground corresponds
to Code 4096 and the maximum amplitude corresponds to
Code +4095.

Figure 39. Pseudo Differential Inputs
Figure 40 and Figure 41 show the typical voltage range on the
VIN input for the different analog input ranges when
configured in the pseudo differential mode.
For example, when the AD7323 is configured to operate in
pseudo differential mode and the ±5 V range is selected with
±16.5 V VDD/VSS supplies and 5 V VCC, the voltage on the VIN
input can vary from 6.5 V to +6.5 V.
