I am trying to undertsand how to AD5933 works, but I'm having trouble as in the documentation I find two things about setting the Vpp for the excitation voltage quite contradictory:
1) Vpp scales with the Vdd: "VDD*1/3.2=VoltageExcitationOutput(p-p)"
2) Vpp is set by the user using control registers 0x80, 0x81: "The user has the added flexibility to select one of four possible output excitation peak-to-peak ranges by setting Bit D8 and Bit D9 in the control register"
So, how does this actually work?
Thanks to everybody
