- Part of the CAT5120 comparator family.
- Part of the CAT5120 comparator family.
CAT5120, CAT5121, CAT5122
16‐tap Digital Potentiometers (POTs) with 2‐wire Interface
Description
CAT5120/5121/5122 linear-taper digital POTs perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 16-tap points that are digitally controlled through a 2-wire up/down serial interface.
The CAT5120 is configured as a potentiometer. The CAT5121 and CAT5122 are configured as variable resistors. See Pin Configurations for part functionality.
Two resistance values are available: 10 k W and 50 k W. These are available in space-saving 5-pin and 6-pin SC- 70 and SOT- 23 packages.
