I have an evaluation board for AD6645. When I connected and turned on power supply, generators I begin see the digital code on output digital pins of AD6645 through oscilloscope. Then I measure current which consumes AD6645. It's OK. And then I connect to output connector J2 HSDIO PXIe-6556 and the current (net +3P3V) is rising from 80 ma to 160 mA. Has anyone encountered a similar problem (current is rising when connect to digital pins of IC HSDIO)?
