X9C303 - Digitally Controlled Potentiometer

Description

The Xicor X9C303 is a digitally controlled potentiometer (XDCP).

The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory.

The wiper position is controlled by a threewire interface.

Features

  • Solid-state potentiometer.
  • Three-wire serial interface.
  • 100 wiper tap points.
  • Wiper position stored in nonvolatile memory and recalled on power-up.
  • 99 resistive elements, log taper.
  • Temperature compensated.
  • End to end resistance, ±15%.
  • Terminal voltages, ±5V.
  • Low power CMOS.
  • VCC = 5V.
  • Active current, 3mA max.
  • Standby current, 750µA max.
  • High reliability.
  • Endurance, 100,000 dat.
