EVAL-AD5934EB開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

EVAL-AD5934EB屬于開發(fā)板套件編程器的評估演示板及套件。由亞德諾半導體技術有限公司制造生產的EVAL-AD5934EB評估和演示板及套件該系列產品提供了一種方便的方法，在經過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產品系列。

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.
