AD5161BRM50集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

AD5161BRM50屬于集成電路（IC）的數(shù)字電位計。由亞德諾半導體技術有限公司制造生產(chǎn)的AD5161BRM50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)機械電位器或變阻器的可調節(jié)電阻，但通過電子信號而非機械輸入來進行控制。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、自動化和遠程控制信號級模擬電路，而這些電路本來可能會使用機械電位器。

GENERAL DESCRIPTION

The AD5161 provides a compact 3 mm × 4.9 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.
