Key Features

  • Nonvolatile version of the popular DS1267.
  • Low power consumption, quiet, pumpless design.
  • Operates from single 5V or ±5V supplies.
  • Two digitally controlled, 256-position potentiometers.
  • Wiper position is maintained in the absence of power.
  • Serial port provides means for setting and reading both potentiometers.
  • Resistors can be connected in series to provide increased total resistance.
  • 16-pin SOIC and 20-pin TSSOP for surface mount.
