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 k?, 10 k?, 50 k?, and 100 k?), these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments.
