I am using the ADS8584S in a high speed analog acquisition system.
The ADS8584S is set up with CONSTA and CONSTB tied together, CS and RD tied together, 5V power, parallel data mode and +5 and -5 input scale.
The ADS8584S works good and all channels are working. I do have one concerning problem. I am not able to get a data though put faster than 37KHz. If I speed up faster the data from the channels gets shifted over so CH1 is 0 CH2 gets CH1 data and CH4 is lost. I need to collect data at 20KHz and need some averaging behind the data as well so the ADS8584S was attractive with over a 300KHz bandwidth.
I have delays in clock cycles to ensure correct timing and have them set to the minimums that allow proper operation.
I would like to discuss why the throughput of the ADS8584S is so low.
