I have two identical 9912A evaluation board. I supplied all related power sockets with specific powers (3.3 V and 1.8 V) in accordance to datasheet of DDS board. I had used one power supply containing two adjustable voltage channels (3.3 V and 1.8 V). And I observed from monitor of power supply that there was nearly 1 A current at 1.8 V channel. It seems too high for such board. Is it logical or not? What is the maximum current or electrical power for this board totally/ Because I don't wanna damage DDS board.
Another point is control AD9912A eva. board with pc. Can I control two DDS board separately with one pc?
Thanks in advance.
