Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
"I'm studying the ADC converter model ADS8325, an ADC 16bits SAR model, and it will be used for high-precision lab experiments to collect pressure sensors. As the experiment has a high-pressure variation in a short period of time (less than 10 msec), I will need to acquire these data at a high-speed sample rate. My question is, in order to assure, better performance and noise influence, I will need to put a filter in front of the ADC. On page 19 of the ADS8325 documentation attached, there is a paragraph that says: "For AC signals, a digital filter can be used to the falling edge of DCLOCK to capture each bit. low-pass filter and decimate the output codes. This works in a similar manner to averaging; for every, falling CS signal initiates the conversion and data decimation by 2, the signal-to-noise ratio will improve transfer. The first 4.5 to 5.0 clock periods of the 3dB". But I don't know if this is the best approach if I need to analyze this transient which has higher spectrum frequencies. Can you provide any approach in order to guarantee that I can read data in the best way and with low noise influence?"
Please help to advise. Thank you for extending your help.
Kind regards,
Marvin
