CAT5123数据手册集成电路（IC）的数字电位计规格书PDF

描述 Description

The CAT5123 linear-taper digital POT performs the same function as a mechanical potentiometer or a variable resistor. This device consists of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire up/down serial interface.The CAT5123 is configured as a variable resistor.Three resistance values are available: 10 kΩ, 50 kΩ and 100 kΩ.

特性 Features

简介

CAT5123属于集成电路（IC）的数字电位计。由制造生产的CAT5123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。
