About the AD7450 data sheet in Figure 14

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
