AD7764 : ON-Chip Differential Amplifier

I will use the AD7764 to develop a new measurement equipment.

I have a question about the On-Chip differential amplifier of the AD7764.


I want to design the amplifier circuit of the ADC input part in high accuracy.

The input signal to this ADC is a Single-ended.


To design this amplifier circuit in high accuracy, should I design it as shown in Figure 37 in the datasheet?

Or, should I use ADC-Driver such as a ADA49xx without using a On-Chip amplifier of the AD7764?
