EVAL-AD5270SDZ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-AD5270SDZ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-AD5270SDZ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 AD5270/AD52711 are single-channel, 1024-/256-position digital rheostats that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package.

The AD5270/AD5271 ensure less than 1 end-to-end resistor tolerance error and offer 50-times programmable (50-TP) memory.
