How to use ADA-GPIO card with DE1-SoC

Hi Avi,

Please allow me to comment further on top of the last reply from our technical support team a month ago.

For the 2nd question of yours, our ADA-GPIO was designed with transformer configuration to provide the optimum high frequency performance. However, it is for ac coupling application only. You'd have to change the configuration from transformer to differential op amp configuration for dc coupling and that requires huge amount of rework, so there's nothing can be done by changing your code to output DC voltage.

For more details, please refer to page 18 of a datasheet named AD9767.pdf in the system CD. Hope it helps.
