ANALOG DEVICES AD5259BCPZ10-R7

AD5259 is a non-volatile, I²C-compatible 256-position, digital potentiometer. It performs the same electronic adjustment function as mechanical potentiometers or variable resistors. It has enhanced resolution and solid-state reliability. The terms digital potentiometer, VR (variable resistor), and RDAC are used interchangeably. It has a wiper settings which is controllable through an I²C‑compatible digital interface. It 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%. This potentiometer is widely used in application such as LCD panel VCOM adjustment, LCD panel brightness and contrast control, mechanical potentiometer replacement in new designs, programmable power supplies, RF amplifier biasing, automotive electronics adjustment, gain control and offset adjustment, fibre to the home systems, electronics level settings.
