MCP41050集成電路（IC）的數(shù)字電位計規(guī)格書PDF中文資料

MCP41050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MCP41050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 MCP41XXX and MCP42XXX devices are 256-position, digital potentiometers available in 10 k?, 50 k? and 100 k? resistance versions. The MCP41XXX is a single-channel device and is offered in an 8-pin PDIP or SOIC package. The MCP42XXX contains two independent channels in a 14-pin PDIP, SOIC or TSSOP package. The wiper position of the MCP41XXX/42XXX varies linearly and is controlled via an industry-standard SPI interface. The devices consume
