AD5124BCPZ100-RL7集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

AD5124BCPZ100-RL7屬于集成電路（IC）的數(shù)字電位計。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD5124BCPZ100-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 AD5124/AD5144/AD5144A 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.

The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through the RAW and RWB string resistors, allowing very accurate resistor matching.

The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making these devices suitable for filter design.
