GENERAL DESCRIPTION
The AD5161 provides a compact 3x4.9mm packaged solution for 256 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 (5k, 10k, 50k, 100kΩ) these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments.
