MCP41HV31T-503E/ST集成電路（IC）的數(shù)字電位計(jì)規(guī)格書(shū)PDF中文資料

MCP41HV31T-503E/ST屬于集成電路（IC）的數(shù)字電位計(jì)。由微芯科技股份有限公司制造生產(chǎn)的MCP41HV31T-503E/ST數(shù)字電位計(jì)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(guò)電子信號(hào)而非機(jī)械輸入來(lái)進(jìn)行控制。雖然這些器件的電阻可耗散的電能相對(duì)有限，但其電子控制能力有助于小型化、自動(dòng)化和遠(yuǎn)程控制信號(hào)級(jí)模擬電路，而這些電路本來(lái)可能會(huì)使用機(jī)械電位器。
