MCP455集成電路（IC）的數(shù)字電位計(jì)規(guī)格書PDF中文資料

MCP455屬于集成電路（IC）的數(shù)字電位計(jì)。由微芯科技股份有限公司制造生產(chǎn)的MCP455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(hào)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(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，而這些電路本來可能會(huì)使用機(jī)械電位器。

DESCRIPTION OF DEVICE FEATURES

The MCRF450/451/452/455 is a contactless read/write passive RFID device that is optimized for 13.56 MHz

RF carrier signal. The device needs an external LC resonant circuit to communicate wirelessly with the Interrogator. The device is powered remotely by rectifying an RF signal thatis transmitted from the Interrogator and transmits or updates its contents from memory-based on commands from the Interrogator.
