Question
I want to log a analog signal, and save it in a file on a computer.
What is the maximum time the AD7760 EVB & EVAL-CED1Z can record at 2.5 MSPS?
Answer
The AD7760 EVB & EVAL-CED1Z can take a sample set of continuous data that is
500k samples in
length. After this there is a bottleneck in the USB transfer beyond this buffer
size. The file will save (with each sample – represented as the decimal value
of the
ADC output code) for whatever the last batch was sampled at – so it can be done
for 2.5Msps. Note it is only for a batch and won’t do a stream beyond the 500k
samples I mention.
