I'm considering the U3 for a project but I need to know the lowest possible latency from the write command to voltage raise/drop on both digital and analog outputs.
As I could infer from other posts and the documentation, there's a minimum 0.6 ms round trip time for commands that don't read analog inputs, but:
1) For digital outputs, can I assume that the write time is half that time (0.3 ms) being the other half the time to reply the outcome to the host?
2) For analog outputs, there's an old post relating the DAC conversion time to the timer clock. I don't know if that still holds but I'm assuming in the best case I could use a 48MHz clock and an 8 bit DAC to take that time down to ~5 usec. This would be on top of the same 0.3 ms above resulting in 0,303 ms total write time.
3) What about the actual voltage raise/drop? Do you have the specs for the time it takes to bring the voltages from 0 to 5V and vice-versa?
Thanks a lot,
