AD5247BKS100-R2 Datasheet

The AD5247 provides a compact, 2 mm x mm, packaged solution for 128-position adjustment applications. This device performs the same electronic adjustment function as a mechanical potentiometer or a variable resistor. Available in four different end-to-end resistance values 5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ , these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments.
