DS1809:Dallastat

The DS1809 Dallastat is a single, 64-position digital potentiometer which provides both a simple contact closure-controlled interface and a microprocessor-controlled interface. Wiper position is maintained in the absence of power in EEPROM. Wiper setting can be stored automatically or on command. Because it handles both mechanical pushbutton and digital inputs, the DS1809 can adapt to applications with either or both mechanical and processor-controlled interfaces. In either case, digitally controlled resistance values are more reliable and accurate than mechanical potentiometers and can be mounted with automated manufacturing processes, saving time and money.

Key Features
  • Single 64-position potentiometer
  • Digital or pushbutton control
  • Two nonvolatile wiper storage options
  • Operating ranges:
    • -40ºC to +85ºC
    • 4.5V to 5.5V
