hi engineers and tinkers,
I am looking for a 5 Channel ADC with 2 MSPS (not strictly, can also be more) that I can connect to my computer via USB to process sensor signals in real time.
The input voltage range for each channel should be around +/- 10 Volts.
Now I assume USB 2.0 has a maximum usable data rate of ~ 40 MB/s = 320 Mbit/s. So in theory I can easily have a resolution of 16 bits then but I am really not sure what practical problems I could encounter.
Another question is, if I can programm the ADC such that it only samples data and transfers it if there is a signal present on one certain and fixed channel (e.g. Channel 1). There I would have to set a threshold for channel 1 and once it is exceeded the sampling on all channels and the data transmission occurs. After a certain time, say 0.5 ms, the ADC should wait for another signal on channel 1 and stop the processing.
Do you know if there is a simple ADC board which I can buy for this application?
Gracias!
