Descriptions:

The X9312WS is a digitally controlled potentiometer (DCP) that functions similarly to a mechanical potentiometer but is electronically adjustable via a simple 3-wire interface. It features non-volatile memory, allowing it to retain the wiper position when power is removed.

Features:

  • 100 Tap Points for precise adjustment
  • Non-Volatile Wiper Storage
  • Low Power Consumption
  • Wide Operating Voltage Range (2.7V to 5.5V)
  • Compact SOIC-8 Package
  • Increment/Decrement Control via simple up/down signals
  • Endurance: 100,000 data changes per bit
  • Applications:
  • Volume control
  • LCD contrast adjustment
  • Programmable voltage references
  • Sensor calibration

This part is now obsolete but was widely used in applications requiring digitally adjustable resistance.
