AD5273EVAL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

AD5273EVAL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AD5273EVAL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(chǎn)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(guān)模式電源)，評估平臺可組合為一個單獨的產(chǎn)品系列。

GENERAL DESCRIPTION

The AD5273 is a 64-position, One-Time-Programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve the permanent program setting. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It allows unlimited adjustments before permanently setting the resistance values. The AD5273 is programmed using a 2-wire, I2C compatible digital control. During the write mode, a fuse blow command is executed after the final value is determined, therefore freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer).
