What is the default current at idac output?
We design a system using ad9850,
We set RSET 3.01Kohm and idac output side resistor is 50ohm.
We are getting a voltage of 5v and our vdd is 5v.
What is the issue???
Can I have a circuit schematic at the output stage of your design..
Yes sure. I have attached the schematics.
Maybe it has something to do with the states of your digital pins, have you ensured that the RESET pin was low during the operation? You should also try terminating the other side of the complementary input if you are not using it, such as this:
This was taken in the datasheet.
Yeah there is a issue in digital pin states, clash between mcu and dds rails.
if i connect avdd to 5v and dvdd to 3.3v(bcoz mcu output rail is 3.3v)
Whether there is any problem???
