32-Tap MiniPot™ Digital Potentiometer (DPP™) with 2-Wire Interface Описание продукта The CAT5110 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 CAT5110 is configured as a potentiometer. Three resistance values are available: 10kΩ, 50kΩ and 100kΩ. The CAT5110 is available in space saving 5-pin and 6-pin SC-70 and SOT-23 packages. Отличительные черты
