描述 Description

The MCP401X devices are volatile, 6-bit (64 wiper steps) digital potentiometers with a simple up/down serial interface. The MCP401X devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. The MCP4011 device offers a voltage divider (potentiometer), with all terminals available on pins. The MCP4012 is a true rheostat, with both nodes of the resistor available on pins. The MCP4013 device offers a voltage divider (potentiometer), with one terminal connected to ground. The MCP4014 device is a rheostat mode device, with one terminal of the resistor connected to ground. The MCP401X family of devices are available with resistor values of 2.1kΩ, 5kΩ, 10kΩ and 50kΩ. These devices operate from a single 1.8V-5.5V supply and draw less than 1 μA while operating in the static state.

簡介

MCP4014屬于集成電路（IC）的數字電位計。由制造生產的MCP4014數字電位計數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。
