AD9634芯片的驱动芯片ADA4930-1的参考电路问题

Question

According to the driver circuit design provided in the AD9634 chip manual, the resistance and feedback loops of the ADA4930-1 chip are very different from the resistance and feedback loops in the circuit design provided in the ADA4930-1 chip. The specific difference is shown in the figure below. The RG resistance value in the figure does not match the one described in the ADA4930-1 chip manual, and the circuit designs in the two chip manuals are different. How should this problem be solved?

I am not familiar with multisim software. I know that the DIFFAMP-CALC tool will get you a circuit that works in the setup you want. You can then wire the circuit in LTSpice with the values from DIFFAMP-CALC tool and simulate it. This has worked for me. If you have specific questions about the ADA4930, please post them in the ADC Drivers - EngineerZone (analog.com) forum. I will close this discussion now.
