The AD5290 is a compact +30 V / ±15 V 256-position digital potentiometer suitable for high voltage, high-performance applications. It features 256 positions and resistance ranges of 10 kΩ, 50 kΩ, and 100 kΩ, and can operate with a single supply voltage of +4.5 V to +30 V or a dual supply voltage of ±4.5 V to ±15 V. The product uses a 3-wire SPI-compatible serial interface and offers low temperature coefficient, low total harmonic distortion, and midscale preset functionality. It is available in a compact MSOP-10 package and can be used in applications such as high voltage DACs, programmable power supplies, programmable gain and offset adjustment, programmable filters and delays, actuator control, audio volume control, and mechanical potentiometer replacement.
The AD5290 is a high‑voltage, high‑performance digital potentiometer available in 10 kΩ, 50 kΩ, and 100 kΩ resistance options. It operates from +4.5 V to +30 V in single‑supply mode or +4.5 V to +15 V in dual‑supply mode and is qualified for an automotive temperature range of –40 °C to +125 °C. The device is offered in a compact MSOP‑10 package and features a 3‑wire SPI‑compatible serial interface.
