MAX5418
Description
The MAX5417/MAX5418/MAX5419 nonvolatile, lineartaper, digital potentiometers perform the function of a mechanical potentiometer by replacing the mechanics with a simple 2-wire digital interface, allowing munication with multiple devices. 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 fast-mode I2C-patible serial interface allows munication at data rates up to 400kbps, minimizing board space and reducing interconnection plexity in many applications. Each device is available with one of four factory-preset addresses (see the Selector Guide) and features an address input for a total of eight unique address binations. The MAX5417/MAX5418/MAX5419 provide three nominal resistance values: 50k Ω (MAX5417), 100k Ω (MAX5418), or 200kΩ (MAX5419). The nominal resistor temperature coefficient is...
