The AD5290 is a high voltage, high performance digital potentiometer with 256 positions and resistance ranges of 10kΩ, 50kΩ, and 100kΩ. It can operate on a single supply of +20 V to +30 V or dual supplies of ±10 V to ±15 V. It utilizes the low temperature coefficient iCMOS™1 process technology and features a compact MSOP-10 package and automotive temperature range of -40°C to +125°C.
The AD5290 digital potentiometer provides 256 discrete positions and is available in 10 kΩ, 50 kΩ, and 100 kΩ resistance options. It operates from a single supply of +4.5 V to +33 V or a dual supply of ±4.5 V to ±16.5 V and is qualified for automotive temperature ranges of –40 °C to +125 °C.
Its 3‑wire SPI‑compatible serial interface allows easy integration into microcontroller‑based systems. The device features a low temperature coefficient of 35 ppm/°C, typical THD of 0.006 %, and bandwidth up to 470 kHz depending on the resistance version. The compact MSOP‑10 package makes it suitable for space‑constrained designs.
