The AD5933 is a high precision impedance converter systemsolution that combines an on-board frequency generator witha 12-bit, 1 MSPS, analog-to-digital converter (ADC). Thefrequency generator allows an external complex impedance tobe excited with a known frequency. The response signal fromthe impedance is sampled by the on-board ADC and a discreteFourier 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.Once calibrated, the magnitude of the impedance and relativephase of the impedance at each frequency point along the sweepis easily calculated. This is done off chip using the real andimaginary register contents, which can be read from the serialI2C interface.A similar device, also available from Analog Devices, Inc., is theAD5934, a 2.7 V to 5.5 V, 250 kSPS, 12-bit impedance converter,with an internal temperature sensor and is packaged in a 16-lead SSOP.
