About the AD7450 data sheet in Figure 14

Question

Hi Approximately the same figure is posted on the data sheet of AD 7450 and AD 7450 A. However, I think there is a mistake in the figure of the AD 7450 data sheet. My customer is completely confused. I want an engineer's ruling. 
 
 AD7450 Rev.A (AD8138 INV.OUT to AD7450 Vin+)

AD7450A Rev.D 
 
 Best regards

Hi Mochi, 
 There no significant effect if the signal is inverted or not especially in AC performance. But I recommend to use the circuit in figure 34 of AD7450A Rev D datasheet where in the non-inverting output of the amplifier is connected to non-inverting input of the ADC and the other way around with inverting output of the amplifier and inverting input of the ADC. 
 Regards, 
 Daryl
