Goodmorning, I've been using an old soundcard as low frequency (below 100Hz) AWG so I removed capacitors to get DC output.
Now I would like to move to a serial/USB device but current soundcards and/or USB DAC have output frequency starting from 20Hz.
I need DAC with bipolar power supply.
Taking a look to DAC1280 datasheet I think it's suitable for my purposes but I can't find evaluation board.
May someone help me and tell me if available similar device/evaluation board?
Thanks.
