Question about AD9751's Iout is a of about 0.5V when power on.

Hello Justin.Jung ,

Thank you for your interest in AD9751. Would you be able to share your schematic? 

Many Thanks, 

Lorenz

I send you the schematic you requested.

Thank you for your support.

Hello Justin,

Thanks for sharing your schematic. What is the output amplitude that you are targeting? AD9751 has an output compliance of -1V to 1.25V and IoutFS*Rload should be within this range. At 20mA, I would suggest an rload of 50 ohm for 1V or 62.5 ohm for the max 1.25V.

As for the momentary change in IoutA after power up, you are correct, this is inevitable for this part. 

Many Thanks, 
Lorenz
