AD5171BRJZ10-R7集成電路（IC）的數字電位計規(guī)格書PDF中文資料

AD5171BRJZ10-R7屬于集成電路（IC）的數字電位計。由亞德諾半導體技術有限公司制造生產的AD5171BRJZ10-R7數字電位計數字電位器是一系列集成電路器件，可提供類似于傳統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 AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer 2 that uses fuse link technology to achieve the memory retention of the resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory settings in the digital potentiometer. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors.
