On my design, two differential signals: one from a Demodulator (ADL5380) and the other from a DAC (AD9117) go to a differential amplifier (ADA4930). So that the output of both Demod and DAC should have the same common mode level and swing. The desired common-mode output is 1.2 V with the swing of 1 Vp-p.
What is the best way to get the above spec? Do I have to use the internal common mode resistors or the external resistors?
What output current should I use?
The DAC AVDD will be tied to 3.3 V.
Thanks in advance
