AD5143BCPZ100-RL7集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

AD5143BCPZ100-RL7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AD5143BCPZ100-RL7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 AD5123/AD5143 potentiometers provide a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8 and up to ±6 mA current density in the Ax, Bx, and Wx pins. The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching.
