AD5934YRSZ

250 kSPS, 12-Bit Impedance Converter,  Network Analyzer

数据采集ADC/DAC – IC 12bit 250ksps Impedance Cnvtr

GENERAL DESCRIPTION AD5934YRSZ

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

FEATURES AD5934YRSZ

Programmable output peak-to-peak excitation voltage to a

maximum frequency of 100 kHz
