Analog Devices AD5259 Digital Potentiometer Data Sheet
The AD5259 is a compact, nonvolatile digital potentiometer designed for applications requiring electronic adjustment similar to mechanical potentiometers but with enhanced resolution and solid-state reliability. It features an I2C-compatible interface that allows control of the wiper settings and reading back register content via SDA and SCL pins.
The device offers end-to-end resistance values of 5 kΩ, 10 kΩ, 50 kΩ, or 100 kΩ with a stored tolerance accuracy of 0.1%. It is available in two packages: the Thin LFCSP-10 (3 mm x 3 mm) and the Compact MSOP-10 (3 mm x 4.9 mm). A separate VLOGIC pin provides increased interface flexibility, allowing operation with logic voltages different from the analog supply.
