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.
