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.

Description

CAT511 0/511 8/511 9/5123/5124/5125 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 potentiometers.

The CAT5118/19/23/24 are configured as variable resistors.

Three resistance values are available: 10k, 50k and 100k. All devices are available in space-saving 5-pin and 6-pin SOT-23 packages. The CAT511 0/511 8/511 9 are also available in the SC70 package.
