AD7765 DiffAmp max input signal

I am about to use AD7765 and i am confused with max input signal level for differential amp.

The datasheet on page 18 says :

The common-mode input at each of the differential amplifier inputs (Pin VINA+ and Pin VINA−) can range from−0.5 V dc to

2.2 V dc. The amplifier has a constant output common-mode voltage of 2.048 V, that is, VREF/2, the requisite common-mode voltage for the modulator input pins (VIN+ and VIN−).

but next paragraph says:

Figure 30 shows the signal conditioning that occurs using the differential amplifier configuration detailed in Table 7 with a

±2.5 V input signal to the differential amplifier. The amplifier in this example is biased around ground and is scaled to give

±3.168 V p-p (−0.5 dBFS) on each modulator input with a 2.048 V common mode.

and follows nice picture with signal +-2.5V, but limits for amp are -0.5V to 2.2V dc.

I would like to measure signal +-2V.

Thanks in advance to any help.
