Hi, ADI

>I have a problem when used AD1937 on my board.We can saw a clear distortion when we play the sine wav file, we also use the Cool Edit Pro tools to review the soure file, it's a good sine wavform, not found any distortion from the begining to the last.

>Attached the hardware circuit for AD1937,the AD1937 code and driver we used and also the output waveform we probed on audio jack.

 

Thanks

Ryan
