AD5262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AD5262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 AD5260/AD5262 provide a single- or dual-channel, 256-position, digitally controlled variable resistor (VR) device.* These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5260/AD5262 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register.
