Hi, I'm looking for help with a project I'm working on using the AD1851 DAC. To test it I am trying to play a wav file that is just a tone but no matter what i play i just get a nonsensible output.
I am outputing to the DAC using a general purpose DSP from motorola that reads the flash memory and sends it to the DAC. I am sending the data at 7.5MHz which is within the 12.5MHz spec. Ive pretty much checked over everything including send MSB first.
I am using a timer interrupt that sends 16 bits every 22.727272us which is 44000Hz.
I think the problem is due to two's complement but for all i know it could be the timing in general or some other problem.
Thanks, Blazin

Hi
Can you send me your code. We can check it together because I'm doing with this device. Thanks
