Hello, My work is related
with bio-sensor. I am very interested in the AD5933 and want to use it in my
design.

Because I am a biologists but not a expert in electrical engineering, I do not
know how to connect AD5933 with PC. I learned that there is evaluation board of
AD5933
(http://www.analog.com/zh/evaluation/eval-ad5933/eb.html) and impedance
analyser based on AD5933
(http://www.analog.com/zh/content/reference_design_2/fca.html??%20AD5933). My
question is what is the difference between these two boards? Which one can be
used directly for the impedance analysis?

Moreover, how many electrodes is required for AD5933, two-electrodes or three
electrodes system? What is the minimum excitation signal amplitude (Vtest) of
AD5933?
