USB digital I/O

[hanh]

I intend to use an NI -USB digital I/O and an ADC, DAC (12bit) to make a DAQ card . How about  the maximum sample rate,analog out update rate ? Which USB digital I/O is suitable  for my card ?

Hi Hanh,

The USB-6501 is possibly a good fit since it has 24 channels and you will be creating two 12-bit circuits.

If you want features like programmable powerup states and more channels, the DAQPad-6507 would be a better fit.
