The AD5290 is one of the few high voltage, high performance, and compact digital potentiometers1in the market at present. This device can be used as a programmable resistor or resistor divider. The AD5290 performs the same electronic adjustment function as mechanical potentiometers, variable resistors, and trimmers, with enhanced resolution, solid-state reliability, and superior temperature stability.With digital rather than manual control, the AD5290 provides layout flexibility and allows closed-loop dynamic controllability.The AD5290 is available in MSOP-10 package and has 10 kΩ, 50 kΩ, and 100 kΩ options. All parts are guaranteed to operate over the –40°C to +125°C extended automotive temperature range.ApplicationsHigh voltage DACProgrammable power supplyProgrammable gain and offset adjustmentProgrammable filters and delaysActuator controlAudio volume controlMechanical potentiometer replacement1The RDAC segmentation is protected by U.S. Patent Number 5,495,245.
