EVAL-AD9837SDZ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(dǎo)體技術(shù)有限公司制造生產(chǎn)的EVAL-AD9837SDZ評估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗(yàn)證的實(shí)施環(huán)境中評估某些重點(diǎn)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(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)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(dú)特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評估平臺可組合為一個(gè)單獨(dú)的產(chǎn)品系列。

GENERAL DESCRIPTION

The AD9837 is a low power, programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable,

allowing easy tuning. The frequency registers are 28 bits wide: with a 16 MHz clock rate, resolution of 0.06 Hz can be achieved; with a 5 MHz clock rate, the AD9837 can be tuned to 0.02 Hz resolution.
