CAT5120: Digital Potentiometer (POT), 16-Tap, with 2-Wire Interface

Description: CAT5120 linear-taper digital POT performs the same...
  • CAT5120 linear-taper digital POT performs the same function as a mechanical potentiometer or a variable resistor. This device consists of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire up/down serial interface.

    The CAT5120 is configured as a potentiometer. See Pin Configurations for part functionality.

    Three resistance values are available: 10 kΩ , 50k Ω and 100 kΩ.
