DS1869 Dallastat、3V数字电位器

DS1869概述

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.
