Description
General part information
MAX5422 Series
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™-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 interconnection complexity in many applications.The MAX5422/MAX5423/MAX5424 provide three nominal resistance values: 50kΩ (MAX5422), 100kΩ (MAX5423), or 200kΩ (MAX5424). The nominal resistor temperature coefficient is 35ppm/°C end-to-end and only 5ppm/°C ratiometric. This makes the devices ideal for applications requiring a low-temperature-coefficient variable resistor, such as low-drift, programmable gainamplifier circuit configurations.The MAX5422/MAX5423/MAX5424 are available in a 3mm x 3mm 8-pin TDFN package, and are specified over the extended -40°C to +85°C temperature range.ApplicationsAudio Volume ControlLiquid-Crystal Display (LCD) Contrast ControlLow-Drift Programmable FiltersLow-Drift Programmable-Gain AmplifiersMechanical Potentiometer Replacements
