Characteristics subject to change without notice
CAT5120/5121/5122 linear-taper digitally programmable
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 32-tap points that are digitally controlled through a
2-wire up/down serial interface.

The CAT5120 is configured as a potentiometer. The
CAT5121 and CAT5122 are configured as variable
resistors. See Pin Configurations for part functionality.
Three resistance values are available: 10k , 50k and
100k . These are available in space-saving 5-pin and
6-pin SC70 and SOT-23 packages.
