Hello there,
I am using the AD1939 to drive a differential buffer and would like to know what is the output impedance of the AD1939 in order to adjust my resistors properly. I tried the datasheet but this information is missing.
Thank you,
Fernando.

I have not actually measured the output impedance directly. So the best I can do is to mention that the specifications are measured with a 3k1 ohm load on each pin.
