• The AD5933 is a high-precision impedance converter system solution that integrates an on-chip frequency generator with a 12-bit, 1 MSPS analog-to-digital converter (ADC). The signal generated by the frequency generator is used to excite the external complex impedance, and the response signal of the external impedance is sampled by the on-chip ADC and then processed by the on-chip DSP for discrete Fourier transform (DFT). The DFT algorithm returns a real (R) data word and an imaginary (I) data word at each frequency.

  After calibration, it is easy to calculate the impedance amplitude and relative phase of each scan frequency point. The calculation is done off-chip using the real and imaginary register contents, which can be read from the serial I2C interface.

  Analog Devices also offers a similar device, the AD5934, a 2.7 V to 5.5 V, 250 kSPS, 12-bit impedance converter with a built-in temperature sensor and a 16-pin SSOP package.
