CAT5269集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

CAT5269屬于集成電路（IC）的數(shù)字電位計。由安森美半導(dǎo)體公司制造生產(chǎn)的CAT5269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。

Description

The CAT5269 is two digital POTs integrated with control logic and 18 bytes of NVRAM memory. Each digital POT consists of a series of 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.
