The AD5291 and AD5292 are single‑channel digital potentiometers offering 256‑ or 1024‑position resolution, ±1 % resistor tolerance, and 20‑time programmable non‑volatile memory. They operate from a wide voltage range, supporting both single‑supply (9 V to 33 V) and dual‑supply (±9 V to ±16.5 V) configurations, and are available in 20 kΩ, 50 kΩ, and 100 kΩ nominal resistance options.
These devices are suited for applications such as mechanical potentiometer replacement, instrumentation gain/offset adjustment, programmable voltage‑to‑current conversion, and audio volume control. The datasheet includes detailed electrical characteristics, timing specifications, pin descriptions, and test circuits to aid designers.
