COMMENT
Stresses above those listed under "Absolute Maximum Ratings" maycause 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


CAT5121 linear-taper digitally programmable potentiometer performs the same function as a mechanical potentiometer or a variable resistor. This device consists 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 CAT5121 is configured as a variable resistor. 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 SC-70 and SOT-23 packages.
