MCP41HV51T-502E/ST集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

MCP41HV51T-502E/ST屬于集成電路（IC）的數(shù)字電位計。由微芯科技股份有限公司制造生產(chǎn)的MCP41HV51T-502E/ST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。
