    Thread Summary
    
                The user asked for a 4-wire impedance measurement circuit for the AD5934, with an impedance range of 50 to 250 ohms. The final answer provided guidance on ensuring the signal amplitude at the ADC input is within the specified range and discussed the importance of the clock frequency and the DFT unit's accuracy. The user also encountered issues with the real and imaginary parts of the impedance measurements, which were addressed by converting the hex values to decimal and accounting for the sign bit. The user was informed that multiple AD5934 ICs cannot be used on a single I2C bus due to having the same address, and a TCA9545A I2C bus switch was suggested as a solution.

    I saw the reference design file CN0349 and CN0217, I think both are 2-wire implementation of the AD5P3x family IC. Can I get the circuit reference for the 4-wire implementation, with impedance range of 50 to 250 ohm. 
    

    Help will be highly appreciated.
