AD5162EVAL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

AD5162EVAL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(chǎn)的AD5162EVAL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 AD5162 provides a compact 3 mm × 4.9 mm packaged solution for dual, 256-position adjustment applications. This device performs the same electronic adjustment function as a 3-terminal mechanical potentiometer. Available in four end-toend resistance values (2.5 k?, 10 k?, 50 k?, 100 k?), this low temperature coefficient device is ideal for high accuracy and stability-variable resistance adjustments. The wiper settings are controllable through an SPI digital interface. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.1
