Dual, 256-Tap, Nonvolatile, I2C-Interface, Digital Potentiometers

General Description The MAX5477/MAX5478/MAX5479 nonvolatile, dual, linear-taper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 2-wire digital interface. Each device performs the same function as a discrete potentiometer or var
