MAX5422 Datasheet | Maxim Integrated

.DataSheet.co.kr 19-3371; Rev 0; 7/04 256-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 SPI™-patible 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-patible serial interface allows munication at data rates up to 5MHz, minimizing board space and reducing...
