Description

The CAT5118 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 CAT5118 is configured as a variable resistor. Three resistance values are available: 10 kΩ, 50 Ω, and 100 kΩ.
