The AD5247 is a 128-position I2C®-compatible digital potentiometer with four end-to-end resistance options: 5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ. It is available in a miniature SC70-6 package and requires a single supply voltage of 2.7 V to 5.5 V. The device operates over a wide temperature range of –40°C to +125°C.
The AD5247 provides a compact 2 mm × 2.1 mm solution for 128‑position adjustment applications, functioning like a mechanical potentiometer or variable resistor. It is available in four end‑to‑end resistance options (5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ) and is suited for high‑accuracy, stable variable resistance adjustments in sensor, RF, and LCD applications.
The device operates from a single 2.7 V to 5.5 V supply, draws only a few picoamps of current, and works over –40 °C to +125 °C. It features an I²C‑compatible two‑wire serial interface for full read/write of the wiper register, includes ESD protection, and is supplied in an ultra‑compact SC70‑6 package. Detailed specifications, timing diagrams, pin configuration, and typical performance curves are provided in the document.
