I am using AD9858 DDS chip. I feel confused about the 2 pins of IOUT , and also the 2 pins of ~IOUT(complementary).
Are the 2 pins IOUT are internal connected or I should connected them extenally. Or , they do not need to be connected.
I also do not know how to design the DAC output circuit. The DAC output compliance range is (AVDD − 1.5 V) to (AVDD + 0.5 V). So I can I convert the current output to voltage output? The outputs are differential open collector, so how to design it?ad9858
