    Thread Summary
    
                The user inquires about using an AC coupling capacitor in series with the DAC output of the ADV7390. The final answer confirms that series capacitors can be used to block DC current and remove DC offset, but emphasizes the need to place external filter and buffer components close to the ADV7390 to minimize noise and trace capacitance effects. The user's understanding is correct: AC coupling is possible, but the receiving side must be evaluated, and ADI does not guarantee this configuration as it is outside the datasheet specifications.

    Hi,all.
    we have question of ADV739x DAC output circuit.
    Is it possible to use a circuit configuration like the following diagram, where a capacitor is inserted in series with the DAC output of the ADV7390?
    

    

     
    

    best regards
    AimPoint.
