CAT5241集成電路（IC）的數(shù)字電位計(jì)規(guī)格書PDF中文資料

CAT5241屬于集成電路（IC）的數(shù)字電位計(jì)。由安森美半導(dǎo)體公司制造生產(chǎn)的CAT5241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(dòng)化和遠(yuǎn)程控制信號級模擬電路，而這些電路本來可能會(huì)使用機(jī)械電位器。

DESCRIPTION

The CAT5241 is four Digitally Programmable Potentiometers (DPPs?) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of a series of 63 resistive elements connected

between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches. A separate
