EVAL-AD5290EBZ: Compact +30V/±15V 256-Position Digital Potentiometer

The AD5290 is a low cost, compact 2.9 mm × 3 mm +30V/±15V, 256-position digital potentiometer. This device performs the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.

The wiper settings are controllable through an SPI compatible digital interface. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.

The AD5290 is available in 10k, 50k, and 100kOhm in compact MSOP-10 package. AD5290 can be operated from a single supply to +30 V or dual supply to ±15 V. All parts are guaranteed to operate over the automotive temperature range of -40°C to +125°C.
