AD5933YRSZ - Brand New Analog Devices Direct Digital Synthesis (DDS)
-
Description
The AD5933YRSZ is a high precision impedance converter system solution that combines an on-board frequency generator with a 12-bit, 1 MSPS, analog-to-digital converter (ADC). It is categorized under direct digital synthesis (DDS) products. 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.
