ADI AD5290YRMZ50-R7

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.
