2 single input simultaneous sampling

Started by Eric Cheng December 5, 2003

Using the THS12082, how does this work?

I have signals being sampled from AINP and AINM. Register is set to auto read
from the 2 channels.

I have tried plotting my buffer contents and it corresponds with the 2 signals
that are coming in. However, I wish to analyze them both separately.

So I've tried reading only read every other value of the buffer to get input
AINP which I do. Then the values that are left should correspond to AINM.
However they do not. It produces a signal that is of the same amplitude but of
the order of double the frequency.

Any thoughts/suggestions would be greatly appreciated.
