AD5934YRSZ, 12-битный преобразователь импеданса, анализатор сети, 2.7В до 5.5В, SSOP-16

The AD5934YRSZ is a 250 kSPS 12-bit Impedance Converter Network Analyser that combines an on-board frequency generator with a 12-bit, 1 MSPS, analogue-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.

• Programmable output peak-to-peak excitation voltage
• Programmable frequency sweep capability
• Frequency resolution of 27bits (&lt,0.1Hz)
• Impedance measurement range from 1kR to 10MR
• Phase measurement capability
• 0.5% System accuracy
