DS1866中文资料对数调节电位器数据手册ADI规格书

描述 Description

The DS1866 is designed for simple, low-cost trimming or volume control using either processor manual control inputs. The three-terminal parallel interface provides eight wiper positions, each giving 5dB per step.
This 10kΩ potentiometer can operate from either 3V or 5V supplies and throughout the industrial temperature range. This low-cost part is ideal for cost-sensitive applications.
Digital potentiometers replace mechanical function with digital reliability, accuracy, and automatic control with a processor. The DS1866 provides digital function with simplicity and economy.

简介

DS1866属于集成电路（IC）的数字电位计。由ADI制造生产的DS1866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。
