sampling rate of ADUC842

Mayuri Ghosalkar

hello,

I need to set a sampling rate of 200hz in ADUC842.

As per my understanding,the minimum rate which we can set is in some KSPS

Can you pls provide me some help?

Regards,
Mayuri

    If you do run the ADC at 2000 samples/second, then you obviously have to throw a way 9 out of 10 of all samples. You will get your 200 valuable samples. Maybe, just maybe (depending on type of measurement) you could pick up all 10 samples and compute the average.

    Same if you run the ADC in single-conversion mode and have a 200Hz timer interrupt to start the conversion.

    So what exactly is your problem? What do you have issues with? Where are you stuck? What is holding you back?

    "200 Hz is the frequency"

    So what's the difference between sampling at 200 Hz, or sampling at 400 Hz and ignoring every other sample?
    Or sampling at 2000 Hz, and just using every tenth sample?
