CAT5120: 16-Tap MiniPot™ Digital Potentiometer (DPP™) with 2-Wire Interface
Описание продукта
CAT5120 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 CAT5120 is configured as a potentiometer. See Pin Configurations for part functionality.
Three resistance values are available: 10 kΩ , 50k Ω and 100 kΩ. These are available in space-saving 5-pin and 6-pin SC-70 and SOT-23 packages.
