AD9634芯片的驱动芯片ADA4930-1的参考电路问题

Hi, these are essentially two different setups. the best way to design your circuit would be to use the DIFFAMP-CALC tool 

Hi, I used Multisim software to simulate and analyze the two circuits, and the output of the circuit described in the chip manual of the ADA4930-1 chip in the simulated circuit is a nice sine waveform, but the output waveform of the reference circuit in the chip manual of the AD9634 chip is a bit strange, can this indicate that there is a big problem with the reference circuit in the chip manual

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.
