Maxim Integrated MAX5489EUD

Description
The MAX5487/MAX5488/MAX5489 are dual, linear-taper, digital potentiometers that function as mechanical potentiometers with a simple 3-wire SPI-compatible digital interface. These devices feature a nonvolatile memory (EEPROM) to return the wipers to their previously stored positions upon power-up. The MAX5487 has an end-to-end resistance of 10kΩ, while the MAX5488 and MAX5489 have resistances of 50kΩ and 100kΩ, respectively. They have a low 35ppm/°C end-to-end temperature coefficient and operate from a single 2.7V to 5.25V supply.
