GENERAL OVERVIEW
The AD5246 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 variable
resistor. Available in four different end-to-end resistance values
(5 k, 10 k, 50 k, 100 k), these low temperature coefficient
devices are ideal for high accuracy and stability variable
resistance adjustments.
