EVAL-AD5791SDZ controlled with SDP-B Controller Board

Category: Hardware
Product Number: AD5791
Software Version: ACE

Hi,

I'm using EVAL-AD5791SDZ controlled with SDP-B Controller Board (ADSP-BF527 Blackfin controller). When I program the DAC output with ACE dll (AnalogDevices.Csa.Remoting.Clients), I can get the right DC value. But when I write the DAC value repeatedly, the value change at a speed of about 1.4ms. Is this speed limited by the controller software, I wonder how to speedup, use DMA and how to use?

Thank you!

  • Hi  ,

    Yes, the speed of the DAC output is limited by the controller software/firmware (in this case, generic SPI). This is because the evaluation software is only dedicated to validate the functionality…
