The AD5245 is a 256-position I2C®-compatible digital potentiometer with a compact SOT-23-8 (2.9 mm × 3 mm) package, fast settling time, and four resistance values (5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ).
The AD5245 is a 256‑position I²C‑compatible digital potentiometer offered in a compact SOT‑23‑8 package. It provides selectable end‑to‑end resistance values of 5 kΩ, 10 kΩ, 50 kΩ, or 100 kΩ, low temperature coefficient, and low power consumption, making it suitable for replacing mechanical potentiometers in portable designs.
The document includes functional block diagrams, pin descriptions, electrical and timing characteristics, absolute maximum ratings, typical performance graphs, and ordering information for the various resistance versions and the evaluation board.
