描述 Description

The MCP42010 is a dual-channel, 8-bit digital potentiometer features 10kΩ end-to-end resistance value with an SPI serial interface. The wiper position varies linearly and is controlled via the SPI interface. The MCP42010 has outstanding AC and DC characteristics, and consumes <1 μA during static operation. Applications for the MCP42010 digital potentiometer include audio equipment (volume and tone controls), servo-motor control, battery charging and control, communications (line impedance matching), power supplies, instrumentation (gain, offset adjust), LCD contrast control and programmable filters. The MCP42010 is available in 8-pin PDIP and SOIC packages.

簡(jiǎn)介

MCP42010屬于集成電路（IC）的數(shù)字電位計(jì)。由制造生產(chǎn)的MCP42010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。
