HiApproximately 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
