Digitally Controlled Potentiometers – Also known as: DCP, RDAC, Variable Resistor, Voltage Divider, Digital Pot, Digital Potentiometer

Intersil offers the widest selection of low-to-high resolution digitally controlled potentiometers in single dual and quad configurations. Available in both linear and non-linear tapers, these digital potentiometers replace mechanical potentiometers and trim resistors in applications where digital control allows microprocessor interfacing and extended functionality.
