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 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), these low temperature coefficient

devices are ideal for high accuracy and stability variable

resistance adjustments.

The wiper settings are controllable through the I²C compatible

digital interface, which can also be used to read back the present

wiper register control word. The resistance between the wiper

and either end point of the fixed resistor varies linearly with

respect to the digital code transferred into the RDAC¹latch.

Operating from a 2.7 V to 5.5 V power supply and consuming

3 µA allows for usage in portable battery-operated applications.
