256-Tap, Nonvolatile, SPI-Interface, Digital Potentiometers
General Description
The MAX5422/MAX5423/MAX5424 nonvolatile, lineartaper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 3-wire SPIā¢-compatible digital interface.
Each device performs the same function as a discrete potentiometer or variable resistor and has 256 tap points.
The devices feature an internal, nonvolatile EEPROM used to store the wiper position for initialization during power-up.
The 3-wire SPI-compatible serial interface allows communication at data rates up to 5MHz, minimizing board space and reducing interco...
