Each potentiometer is composed of 256 resistive sections.

Key Features

  • Ultra-low power consumption, quiet, pumpless design.
  • Two digitally controlled, 256-position potentiometers.
  • Serial port provides means for setting and reading both potentiometers.
  • Resistors can be connected in series to provide increased total resistance.
  • 14-pin DIP, 16-pin SOIC, 20-pin TSSOP packages.
  • Resistive elements are temperature compensated to ±0.3 LSB relative linearity.
  • Standard resistance values:.
  • DS1267-10 ~ 10 kΩ.
  • DS1267-50 ~ 50.
