DS1869中文资料3V、Dallastat数字电位器数据手册ADI规格书

描述 Description

The DS1869 Dallastat™ provides the same features as the DS1669 but with operational capability for 3-volt systems.
It provides 64 uniform tap points over standard resistive ranges of 10kΩ, 50kΩ, or 100kΩ. The DS1869 can be configured to operate using a single pushbutton, dual pushbutton, or CPU input by varying power-on conditions. Nonvolatile wiper settings are maintained in EEPROM.
Applications for the DS1869 include LCD contrast and backlighting, tone and volume control. As an integrated circuit, the digital potentiometer replaces mechanical potentiometers with digital precision. It has no moving parts to wear out, saves space, reduces heat, and communicates with a processor for flexible and automatic adjustment.

特性 Features

• Wiper position stored in EEPROM
• 3V to 8V differential supply operational range
• 10kΩ, 50kΩ, and 100kΩ versions

简介

DS1869属于集成电路（IC）的数字电位计。由制造生产的DS1869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。
