X9408 - Quad Digitally Potentiometer

Datasheet Summary

Description

The X9408 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit.

The digital controlled potentiometer is implemented using 63 resistive elements in a series array.

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

Features

  • Four Potentiometers in One Package.
  • 64 Resistor Taps per Potentiometer.
  • 2-wire Serial Interface.
  • Wiper Resistance, 40 Typical at 5V.
  • Four Nonvolatile Data Registers for Each Pot.
  • Nonvolatile Storage of Wiper Position.
  • Standby Current < 1µA max (Total Package).
  • VCC = 2.7V to 5.5V Operation V+ = 2.7V to 5.5V V- = -2.7V to -5.5V.
  • 10k, 2.5k End to End Resistances.

DATASHEET X9408 Low Noise/Low Power/2-Wire Bus Quad Digitally Controlled (XDCP™) Potentiometers FN8191 Rev.4.00 January 15, 2009 Description The X9408 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digital controlled potentiometer is implemented using 63 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is controlled by the user through the 2-wire bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and four non-volatile Data Registers that can be directly written to and read by the user.
