MAX5481EUD+

MAX5481EUD+ is a 10-bit, non-volatile, linear-taper digital potentiometer. This programmable voltage-divider and variable resistor perform the function of a mechanical potentiometer but replace the mechanics with a pin configurable 3-wire serial SPI™-compatible interface or up/down digital interface. It feature an internal, non-volatile, electrically erasable programmable read-only memory (EEPROM) that stores the wiper position for initialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 7MHz. Suitable for gain and offset adjustment, LCD contrast adjustment, pressure sensors, low-drift programmable gain amplifiers and mechanical potentiometer replacement applications.
