EVAL-AD5292EBZ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(shù)有限公司制造生產(chǎn)的EVAL-AD5292EBZ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 AD5291 and AD5292 are single-channel, 256-/1024-position digital potentiometers1 that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices are capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1 end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory.

The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.
