AD8400ARZ10-REEL集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

AD8400ARZ10-REEL屬于集成電路（IC）的數(shù)字電位計。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8400ARZ10-REEL數(shù)字電位計數(shù)字電位器是一系列集成電路器件，可提供類似于傳統(tǒng)機(jī)械電位器或變阻器的可調(diào)節(jié)電阻，但通過電子信號而非機(jī)械輸入來進(jìn)行控制。雖然這些器件的電阻可耗散的電能相對有限，但其電子控制能力有助于小型化、自動化和遠(yuǎn)程控制信號級模擬電路，而這些電路本來可能會使用機(jī)械電位器。

GENERAL DESCRIPTION

The AD8400/AD8402/AD8403 provide a single-, dual-, or quad-channel, 256-position, digitally controlled variable resistor (VR) device.1 These devices perform the same electronic adjustment function as a mechanical potentiometer or variable resistor. The AD8400 contains a single variable resistor in the compact SOIC-8 package.
