Description
potentiometers perform the same function as a mechanical
potentiometer or a variable resistor. These devices consist of a fixed
resistor and a wiper contact with 16−tap points that are digitally
controlled through a 2−wire up/down serial interface.
CAT5122 are configured as variable resistors. See Pin Configurations
for part functionality.
These are available in space−saving 5−pin and 6−pin SC−70 and
SOT−23 packages.
