I presume that's +/-5V. How many bits to your converter? As I mentioned,
full scale for 16 bits is +/-32,767 counts, or +/-3.2767e4.

Actually the values got from CCS graph and from graph property dialog I
can change only the time display unit(s,ms,..) and also I used autoscale.
In fact I don't know what is the unit of these values (2.3e+4)whereas the
input from the mains and after attenuated between 0 an 5volt.
Thanks

Good. I'm glad to hear it.
I ask again: what units do your numbers represent? The readings may not
be large at all. How are the numbers obtained? For integers out of a
16-bit bipolar ADC, 2.3e+4 is about 70% of full scale.

What are the units? 2.3e+4 microvolts is not "very high". If you
connected the mains, I would expect smoke.

Hi,
I am using ADS8364EVM and I would like to know why the value of signal
amplitude is very high when the input signal from the mains or function
generator? also I sow in some books that the amplitude of the signal is
very high (2.3e+4,why?
if I used off line data and the plotting of the signal in CCS is ok like
input values.
Thanks.
