The MAX5422/MAX5423/MAX5424 nonvolatile, lineartaper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mecha.
Features
* o Wiper Position Stored in Nonvolatile Memory (EEPROM) and Recalled Upon Power-Up or Interface Command o 3mm x 3mm x 0.8mm TDFN Package o 35ppm/°C End-to-End Resistance Temperature Coefficient o 5ppm/°C Ratiometric Temperature Coefficient o 50kΩ, 100kΩ, and 200kΩ Resistor Values o 5MHz SPI-Compatibl
Applications
* The MAX5422/MAX5423/MAX5424 provide three nominal resistance values: 50k Ω (MAX5422), 100k Ω (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-coe
