AD9361 Aux DAC Output

Hello all,

I have some doubts regarding the output of the AD9361/4  Aux DAC.

What is the output impedance of the AuxDAC?

UG-673 says that "for, stability, place a 0.1uF capacitor at the output of each AuxDAC", this capacitor with the output resistance of the ADC would be a RC filter and I want to make sure that it is ok for my analog output signal.

 

On the other hand, I want to put a buffer for level conversion. The circuit is the attached picture, and the DAC output is simulated with a power supply with series resistance. Please, let me know if this approach is suitable for the AuxDAC.

 

Thank you so much
