Description : 250 kSPS, 12-BIT Impedance CONVERTER, Network Analyzer

GENERAL DESCRIPTION

The AD5934 is a high precision impedance CONVERTER system solution which 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.



FEATURES

Programmable output peak-to-peak excitation voltage to a max frequency of 100 kHz

Programmable frequency sweep capability with serial I2C® interface

Frequency resolution of 27 bits (<0.1 Hz)

Impedance measurement range from 100 Ω to 10 MΩ

Phase measurement capability

System accuracy of 0.5%
