CAT5123: Digital Potentiometer (POT), 32-Tap, with 2-Wire Interface

The CAT5123 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 CAT5123 is configured as a variable resistor.Three resistance values are available: 10 kΩ, 50 kΩ and 100 kΩ.

特性
  • 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
