X9259 - Quad Digitally-Controlled (XDCP) Potentiometers

Description

The X9259 integrates 4 digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.

The digital controlled potentiometer is implemented using 255 resistive elements in a series array.

Between each element are tap points connected to the wiper terminal through switches.

Features

  • Quad.
  • Four separate potentiometers.
  • 256 resistor taps/pot.
  • 0.4% resolution.
  • 2-Wire Serial Interface for write, read, and transfer operations of the potentiometer.
  • Wiper Resistance, 100Ω typical @ VCC = 5V.
  • 4 Nonvolatile Data Registers for Each Potentiometer.
  • Nonvolatile Storage of Multiple Wiper Positions.
  • Power On Recall. Loads Saved Wiper Position on Power Up.
  • Standby Current < 5µA Max.
  • VCC: 2.7V t.
