GENERAL DESCRIPTION
The AD5934 is a high precision impedance converter system
solution that 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.
Once calibrated, the magnitude of the impedance and relative
phase of the impedance at each frequency point along the sweep
is easily calculated using the following two equations:
Magnitude =
2
I
R +
Phase = tan1(I/R)
A similar device, available from Analog Devices, Inc., is the
AD5933, which is a 2.7 V to 5.5 V, 1 MSPS, 12-bit impedance
converter, with an internal temperature sensor, available in a
16-lead SSOP.
