Pseudo Differential Inputs
The AD7321 can have one pseudo differential pair. 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 pin. 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 pin for the different analog input ranges when configured
in the pseudo differential mode.
For example, when the AD7321 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
pin can vary from 6.5 V to +6.5 V.
