Hi all,
I want to use AD5933 for complex impedance measurement. Does anyone have experience related to this topic? Impedance will be in range 1 k to 1 M so there is no need for additional components which small impedance measurement requires.
My main doubt is how to provide wide range value of unknown impedance: resistor Rfb should be variable to avoid internal AD saturation or what?
Thanks in advance.
