Description

The DS1669 Dallastat™ is a single digital rheostat or potentiometer with access to all three potentiometer terminals. The potentiometer has 64 wiper positions with equal or linear resistive step sizes. This device has both positive and negative 8V (max) supply inputs for maximum wiper outputs of ±7.5V. The wiper position is stored in EEPROM for power-up in a known position or to save calibration information. Control access is configurable with a single pushbutton, dual pushbutton, or digital source input.

Key Features		Applications/Uses
Replaces Mechanical Variable Resistors and Potentiometers Electronic Interface Provided for Digital as well as Manual Control Wide Differential Operating Range Up to ±8V Wiper Position Is Maintained in the Absence of Power Available in 8-Pin SO and 8-Pin DIP Packages Standard Resistance Values for Dallastat ~ 10kΩ (DS1669-10) ~ 50kΩ (DS1669-50) ~ 100kΩ (DS1669-100) Operating Temperature Range Extended Industrial: -40°C to +85°C		Audio Volume Control Mobile Phones and PDAs Portable Electronics Replacement for 6-Bit Linear DAC Functions Replacement for Mechanical Potentiometers
