CAT5110: Digital Potentiometer (POT), 32-Tap, with 2-Wire Interface

The CAT5110 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 CAT5110 is configured as a potentiometer.Three resistance values are available: 10kΩ, 50kΩ and 100kΩ.

Features
  • 0.3 µA ultra-low standby current
  • Single-supply operation: 2.7 V to 5.5 V
  • Glitchless switching between resistor taps
  • Power-on reset to midscale
  • 2-Wire up/down serial interface
  • Resistance values: 10 kΩ, 50 kΩ and 100 kΩ
Applications
  • LCD screen adjustment
  • Volume control
  • Mechanical potentiometer replacement
  • Gain adjustment
  • Line impedance matching
