    Hi,
     
    I need to design a current source from AD5930's output...
     
    I read some papers related with my project and i saw for example, 
     
    AD9850's Iout pin conected directly with a converter V/I (MAX535) that is a Transconductance Amplifier
     
    but the AD5930 has too an input called Iout....
     
    My question is..... The ad5930's Iout pin is a voltage or a current point??? or is AD5930's Iout pin equal than AD9850's Iout pin??
     
    Regards

        Hi!
        
 
        Current Output.Unambiguous.
        
 
        Same as AD9850.
        
 
        "This is a high impedance current source output. A load resistor of nominally 200 Ω should be connected between IOUT and AGND. A 20 pF capacitor to AGND is also recommended to act as a low-pass filter and to reduce clock feedthrough. In conjuction with IOUTB, a differential signal is available."
        
 
        m/s MAX535 had resistance , will current transform as voltage.
        
 
        Regards!
