The AD5260/AD5262 are digital potentiometers with 256 positions and different resistance values such as 20 kΩ, 50 kΩ, and 200 kΩ. They have features such as low temperature coefficient, 4-wire SPI-compatible serial data input, single-supply and dual-supply operation. They can be used as replacements for mechanical potentiometers, for gain and offset adjustment in instrumentation, stereo channel audio level control, programmable voltage-to-current conversion, programmable filters, delays, time constants, and more.
The AD5260 (single‑channel) and AD5262 (dual‑channel) digital potentiometers provide programmable resistance values in 256 steps. They replace mechanical potentiometers in applications such as instrumentation, audio level control, programmable voltage‑to‑current conversion, and filter design. Each device supports 5 V‑15 V single‑supply or ±5 V dual‑supply operation and offers a low temperature coefficient of 35 ppm/°C.
The datasheet includes detailed specifications, pin configurations, timing diagrams, absolute maximum ratings, and typical performance curves. It also provides example circuits for current sources, low‑pass filters, and oscillators, as well as ordering information for the 14‑lead and 16‑lead TSSOP packages.
