DEscription
CAT5110/5118/5119/5123/5124/5125 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 poten-
tiometers. 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 CAT5110/5118/5119
are also available in the SC70 package.

Up/Down Control Input. With CS low, a low-to-high transition
increments or decrements the wiper position.
Chip Select Input. A high-to-low CS transition determines the
mode: increment if U/D is high, or decrement if U/D is low.

Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification
is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
