EVAL-AD5247DBZ Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The AD5247 provides a compact, 2 mm × 2.1 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.
