12-Bit Impedance Converter Network Analyzer
AD5934YRSZ, 12-Bit Impedance Converter Network Analyzer , 16 Pin SSOP, Lead-Free, Quantity 2, Analog Devices.
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:
* Bioelectrical impedance analysis
* Complex impedance measurement
* Corrosion monitoring and protection equipment
* Biomedical and automotive sensors
* Material property analysis
* Fuel/battery cell condition monitoring
* Impedance range: 100 Ohms to 10 MOhms
* 0.5% Measurement Accuracy.
* Programmable excitation frequency sweep (up to 100 kHz)
* Real and Imaginary components of each frequency generated (DFT)
* 2.7 V to 5.5 V power supply
* Frequency resolution 27 bits (<0.1 Hz)
* Predetermined frequency sweep capability
