DESCRIPTION
CAT5110/18/19/23/24/25 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 and CAT5125 are configured as
potentiometers. The CAT5118/19/23/24 are configured
as variable resistors.
Three resistance values are available: 10kΩ, 50kΩ and
100kΩ. All devices are available in space-saving 5-pin
and 6-pin SOT-23 packages. The CAT5110/18/19 are
also available in the SC-70 package.
