The AD5934 is a high precision impedance CONVERTER system solution which combines an on-board frequency generator with a 12-BIT, 250 kSPS, ANALOG-TO-DIGITAL CONVERTER (ADC). The frequency generator allows an external complex impedance to be excited with a known frequency. The response signal from the impedance is sampled by the on-board ADC and a discrete Fourier transform (DFT) is processed by an on-board DSP engine. The DFT algorithm returns a real (R) and imaginary (I) data-word at each output frequency.
