MCP4014集成电路（IC）的数字电位计规格书PDF中文资料

MCP4014属于集成电路（IC）的数字电位计。由微芯科技股份有限公司制造生产的MCP4014数字电位计数字电位器是一系列集成电路器件，可提供类似于传统机械电位器或变阻器的可调节电阻，但通过电子信号而非机械输入来进行控制。虽然这些器件的电阻可耗散的电能相对有限，但其电子控制能力有助于小型化、自动化和远程控制信号级模拟电路，而这些电路本来可能会使用机械电位器。

描述 Description

The MCP4011/2/3/4 devices are volatile, 6-bit Digital Potentiometers that can be configured as either a potentiometer or rheostat. The wiper setting is controlled through a simple Up/Down(U/D) serial

interface.
