Description

CAT5119 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 CAT5119 is configured as a variable resistor.Three resistance values are available: 10 kΩ, 50 kΩ and 100k Ω.
