Product Details

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 potentiometers1 or variable resistors, but with enhanced resolution and solid-state reliability.

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 VLOGIC pin 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 bus
