AD5934YRSZ General Description

The AD5934 is a high precision impedance converter systemsolution that combines an on-board frequency generator with a 12-bit, 250 kSPS, analog-to-digital converter (ADC). Thefrequency 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 DSPengine. The DFT algorithm returns a real (R) and imaginary (I)data-word at each output frequency.
