Description

The AD5259 provides a compact, nonvolatile LFCSP-10 (3 mm x 3 mm) or MSOP-10 (3 mm x 4.9 mm) packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors, but with enhanced resolution and solid-state reliability. The terms digital potentiometer, VR (variable resistor), and RDAC are used interchangeably.The wiper settings are controllable through an I2C-compatible digital interface that is also used to read back the wiper register and EEPROM content. Resistor tolerance is also stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%.A separate VLOGICpin delivers increased interface flexibility. For users who need multiple parts on one bus, Address Bit AD0 and Address Bit AD1 allow up to four devices on the same busAPPLICATIONSLCD panel VCOMadjustmentLCD panel brightness and contrast controlMechanical potentiometer replacement in new designsProgrammable power suppliesRF amplifier biasingAutomotive electronics adjustmentGain control and offset adjustmentFiber to the home systemsElectronics level settings
