Analog Devices AD5280/AD5282 Digital Potentiometer Datasheet
The AD5280 (single‑channel) and AD5282 (dual‑channel) are 256‑position, I2C‑compatible digital potentiometers with selectable fixed terminal resistances of 20 kΩ, 50 kΩ or 200 kΩ and a temperature coefficient of 30 ppm/°C. They operate from a +10 V to +15 V single supply or ±5.5 V dual‑supply and include programmable logic outputs and a shutdown function.
The document details electrical characteristics, absolute maximum ratings, thermal resistance, pin configurations, typical performance curves, and an ordering guide. It also covers interface timing, test circuits, and application information such as using the devices for gain control, programmable voltage/current sources, and impedance matching.
