AD9915 PWRDWN short circuit?

Hi,

 

I am trying to set up the AD9915 to work with SPI. When trying to tie the PWRDWN pin (67) to GND my power supply shows a massive spike in current consumption (> 1 A) and the IC gets hot. There is no other connection to that pin, that would cause this behaviour. Is there anything else, that I am missing when using the DDS?

 

Best Regards,

 

Dennis
