DESCRIPTION
CAT5110/5118/5119 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 CAT5110 is configured as a potentiometer. The
CAT5118 and CAT5119 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.
