ADS8364EVM with DSK6711

Started by mabozaed ●February 16, 2005


Hi,
I just bought ADS8364EVM for my project, and I fixed this EVM on
DSK6711. A sine wave signal was applied from function generator to
one channel on EVM. so my question is how to get the output signal
by using CCS, and I have used the example from ti website (SLAA155).
I can see the output but in fact not sine wave it is exactly half
wave rectifier output, the good point here, this wave can be changed
occurring to input, if the input square wave the output will be
square if sine the output will be sine but not complete wave, and
also the wave it is not goes to negative side it is appear just in
positive area. I Changed the data format in the CCS display
properties but still the output is same not good.
There is another note here that is if I increase the input to nearly
1v the output will more distorted.

Thanks a lot for help

I am not familiar with the ADS8364EVM.  Is your input capacitively coupled??
